We've written before about Brainshark's iPad slide show app and today they have announced the availability of SlideShark Team Edition. It adds admin controls, team-wide content sharing, and usage analytics to the individual features found previously.

With Team Edition, sales teams for example can share their slide decks as they tote about their iPads around the countryside. Individuals can still upload PowerPoint slides for their own use too.

Flowtown releases a great social media cheat sheet for those new to social media. Dan Frommer wonders if downloads or discs are more applicable for the next gen XBox. All of this and more in the ReadWriteWeb Weekly Wrap-up.

After the jump you'll find more of this week's top news stories on some of the key topics that are shaping the Web - Location, App Stores and Real-Time Web - plus highlights from some of our six channels. Read on for more.

If you're one of the few Firefox users still on Windows 2000 or still using Windows XP without Service Pack 2 or later, Firefox is going to have to say goodbye. Yesterday, Mozilla's Asa Dotzler announced that Firefox team is moving to a newer version of the Visual Studio toolchain. Once Mozilla moves to Visual Studio 2010, they won't be able to build for Windows 2000, XP RTM or SP1.

I'm somebody who can, uh, go on. At length. About nearly any subject. Ask anyone who's taken one of my classes... or read one of my blog posts once I get on a roll.

So I can understand why I'll get the odd "TL;DR" in response. And I try not to take it personally; instead, I look on it as a reminder to pare my text down, murder my darlings and generally indulge myself a little less.

If you're not smiling in your Facebook photo, your life is probably going to suck in four years time.

Reseachers J. Patrick Seder and Shigehiro Oishi at the University of Virginia in Charlottesville discovered that smile intensity from a single Facebook profile photo in the first semester of college predicted self-reported life satisfaction three and a half years later, at the time of college graduation.

This type of study isn't actually unique to Facebook, however. A 2011 study by Harker and Keltner showed that female students smiling in their college graduation yearbook photos from 1958 and 1960 were reportedly happier 30 years later. A similar study by Abel and Kruger (2010) found that professional baseball players who smiled more intensely in archival photos lived seven years longer than those who didn't smile much.

U.S. Patent # 6,591,353, "Protocol for Communication with Dynamic Memory," tends to refer to a "memory device." The innovation with respect to this device appeared to be the introduction of a synchronous clock. That way, time-multiplexed transfers could take place in a regulated fashion.

But as USPTO documents published today show, the appeals judges found that two existing patents cited by Nvidia qualify as prior art, and moreover, that the teachings demonstrated by those older patents would be inspiration enough for a skilled artisan to apply the teachings to improving synchronous memory the way Nvidia appears to have done.

So, we've shot down SOPA and PIPA. Congratulations Internets for a job well done. Mission accomplished, right? Not so much. While that's two bad pieces of legislation pushed back, there's much more where that came from. Leaving aside existing nastiness like the DMCA, we also have the even nastier Anti-Counterfeiting Trade Agreement (ACTA) (PDF). How bad is it? Bad enough that the European Parliament's rapporteur for ACTA (Kader Arif) resigned over it today (January 27, 2012). Unfortunately for those of us in the United States, President Obama has already ratified ACTA on behalf of the United States.

"Connect it to Facebook, viral spread, boom, boom." I have no idea what that means but I do know that for some reason, I'm still not tired of the Sh*t [fill in the blank] Says meme. This video is for anyone who's spent more than five minutes reading Techcrunch, knows what Y Combinator is and has faced the (sometimes) irrational exuberance of a tech entrepreneur. "Overheard: Time to pivot."

As mobile becomes normal for the Web, location becomes key. The next phase of location apps are live, right there with the user as she goes about her business. When it comes to mapping the outside world, the space is pretty crowded. It's hard to argue with Google Maps, whose free consumer service powers the maps on both dominant smartphone platforms. For businesses, it's crucial to be on the map, and Google Places can't be overlooked.

But there's another frontier of mobile mapping that matters, and the exploration has just begun. Indoor mapping of big buildings - like airports, convention centers, museums and stores - is the El Dorado of mobile location. Google has begun its expedition inside buildings, and businesses can sign up and offer their floor plans. But there's another option: Use a platform like Meridian and build your own inside map. Which is better for business?

People familiar with the matter say that Facebook could file for its initial public offering as soon as next week, according to reports from the Wall Street Journal. The source also says that Facebook is close to picking Morgan Stanley as the lead underwriter. The filing could happen next Wednesday, and the company is aiming for a $75-$100 billion valuation. It is looking to raise $10 billion in stock.

Facebook started in 2004 as a college-only social network. It opened to the public in September 2006, dropping the minimum age requirement from 18-years-old to 13-years-old. In little over seven years, it has grown to a userbase of 800 million people across the globe.

The most controversial measures of concern to Internet users in the final version of the international Anti-Counterfeiting Trade Agreement (ACTA) for most Internet users are 1) that signing governments pledge to allow copyright holders a way to request, under court warrant, personal information about a suspected infringer from that person's ISP; 2) that means will be provided for a rights holder to legally pursue someone suspected of circumventing rights management technologies; 3) that goods crossing countries' borders may be made subject to search and seizure if they're suspected to contain infringing material, with exceptions provided for things like personal luggage.

President Obama signed this treaty on October 1, 2011, effectively ratifying it on behalf of the United States.

The second-most important thing about social media is talking to people. The most important thing is to know whom you're talking to. We can't have a conversation about "authenticity" or "realness" or any other airy social media concept until we understand that there are people listening on the other side of that megaphone, and that's very nice of them to do. In order to get something out of social media, our listeners have to get something out of listening to us.

To give them what they want, it helps to know who they are. With the integration of Google+ into search, Google's social network will become an increasingly important part of the Web. By Google's count, it has 90 million users already. If you want to have a presence in Google search, active participation on Google+ is a good idea. I tested a tool for understanding the Google+ audience today and found some interesting insights.

Anyone who spends their day on the Internet inevitably wonders this question. Should I start publishing later in the day, to hit the after-work traffic? Should I publish earlier in the morning, to catch commuters while they're on the way to work? Or is everything completely random, driven by the off-chance that a post will end up on StumbleUpon and enjoy a slightly longer tail? Social sharing widget Shareaholic looked at its 2011 data, breaking it down to the top 100 days and times for sharing. See the results in Eastern Standard Time.

"We eat with our eyes," Iliana Regan told me, "and then it travels to our brain, and we love the sensation of the taste and the hot. I think it does a lot for the senses." Pretty steamy, right? Food is sexy. There can be no doubt. But just like sex, it's not always pretty. And in food and sex alike, humans love to take pictures.

There are laws about the sex part, but food is not censored in our society. The temptation is strong in the smartphone age to share our daily deeds with the world. It makes them less mundane. Meals are miraculous, really. Food is sacred. It gives life. But the rest of us on the Internet aren't at the table with you. We can't taste how good it is. Sometimes, if the light's not quite right, or you're too close up, what feels really good to you might look really gross to us.
