Social media moves so fast, it's hard to keep up. Here are the week's top stories in scan-friendly format:

Stack Overflow Gets Funding, Changes Name

Stack Overflow has humble roots -- it has existed as a question-and-answer-based resource site for programmers and developers. However, the site is about to go way beyond being a go-to resource for programmers. Stack Overflow has shed its nerdy name and is now known as Stack Exchange. Also, the company announced a new round of funding: $12 million in series B from three notable venture capitalist firms.

What started out as a q&a site for programmers has blossomed into a network consisting of 45 expert sites on a variety of topics ranging from Apple to statistical analysis and photography. All those sites generate impressive traffic including 20 million monthly unique visitors, 95 million page views and nearly 800,000 registered users.

Also good news for sites such as Stack Exchange: With Google's recent algorithm change, the quality conversations should bubble up higher in search results. Google tweaked its search algorithm to counter content farms, meaning less-desirable sites -- pushing products that were SEO optimized -- clouded search results. Stack Exchange will benefit by now outranking the spammy results that showed before.

Even Digital Natives Won't 'Like' Your Company on Facebook

Teenagers are often seen as the most "native" group online. That is, this age group has grown up with Facebook being a part of the daily fabric of their lives, with recent numbers showing that 75% of teens go online on a daily basis. Also, with iPod Touches, mobile phones and gaming consoles, this group practically lives online.

Knowing these usage numbers, one would think this age group would be ripe for social media marketing. However, according to research group Forrester, only 6% of US consumers in the 12-17 age range are interested in interactive brands on Facebook. The study found that, yes, this age group talks about products and services online, but they like to initiate the conversation, rather than having the brand spawn the discussion.

According to the study, 16% of young consumers expect companies to use social tools to interact with them, while 28% expect companies to listen to what they're saying about the brand and respond if they have a question. So the lesson for brands and marketers, when dealing with teens: Don't be obnoxious -- listen and respond, but don't speak first every time.

DailyBooth Hopes to Go Big with Face-to-Face Photo Sharing

Sharing photos online is nothing new. Ever since digital cameras became affordable, those online love to swap photos with friends and families. There seems to be a resurgence with mobile apps such as Instagram and PicPlz, allowing filters and effects to give photos some added zest. DailyBooth is hoping the trend continues with face-to-face pictures as well.

The DailyBooth site and mobile apps enable users (mostly teens and young adults) to share photos of their faces on a daily basis. With front-facing cameras now a standard on devices such as the iPad 2, iPhone 4 and many Android phones, the company hopes more folks decide to upload "booths" every day to share with their online friends. The company has raised $6 million to build the servcice and expand the company.

Would you upload your photo on a daily basis? Social movements sometimes use pictures to note unity around a cause and individuals like to show their changes in appearance, but other than that, what uses would you have for a service such as DailyBooth?

Formspring Goes Mobile, Debuts SMS Service

Formspring, the popular personal Q&A site, has gone beyond its conventional website by launching a mobile utility. The company unveiled a host of SMS features that give users a way to respond and interact with Formspring while on the go.

When enabled, Formspring users can turn SMS alerts on and respond to questions, ask new questions and send out questions to third-party social networking sites via text commands. SMS-based alerts can be customized, making it possible to receive SMS alerts from anyone, only those you follow or not at all; the same goes for receiving responses to your questions. Additionally, users can set hours whereby no alerts will be sent out, to avoid being woken up in the middle of the night.

Why would Formspring use SMS and not a conventional mobile application? Many of Formspring's users are of a younger demographic who may not have access to smartphones. Also, using SMS gives Formspring a universal way to embrace all mobile platforms, rather than build just an iPhone application or Android application.
