A Challenger to LinkedIn, Social Media Olympics and Live Tweeting at Weddings | This Week in Social Media

A Challenger to LinkedIn?

LinkedIn’s biggest competitor just might be a Facebook app that hit 25 million users last week. BranchOut lets users see where their Facebook friends work, using pre-existing Facebook graphs. Like LinkedIn, users populate the platform with their work history, get recommendations and connect with more users. It remains to be seen if the public wants to integrate the job networking functions of Facebook with the “friend” aspect of the platform. Mashable

The Social Media Olympics – Literally

The Super Bowl, Wrestlemania, Major League Baseball Opening Week. Major sporting events dominate social media conversation, but the 2012 London Olympics will be the first truly social Games. At the 2008 Beijing Games, Facebook had a mere 100 million users, while Twitter had six million. This year, Twitter has 140 million users and Facebook a whopping 845 million. The International Olympic Committee launched its online hub last week and is emphasizing social this summer, from following prominent Olympians on Twitter and Facebook (hello @UsainBolt) to earning rewards for participating in the social Olympic community. It’s my guess that the traffic generated from these Games will knock any previous event off the map. Oh, and go Canada (@CDNOlympicTeam)! hub.olympic.org

Twitter: The New Wedding Guest Book?

You can live tweet anything these days – including weddings. A couple in Ohio set up a Twitter station at their reception for guests to sign-in and live tweet from their wedding night. Dave and Chanelle had guests tweet on a Twitter account set up specifically for the wedding, using hashtag #smittywedding. Some of the tweets were sweet, while others were a little, um, you be the judge. How would you feel about enabling guests to live tweet from your wedding? The Knot Blog
