The US government knows social networking is the key to better collaboration between agencies and employees, but has held back because of security concerns. Recently, the government developed security guidelines to make social media more secure.

Links are the Currency of Twitter
According to Zarrella, links were three times more prevalent in RTs over normal tweets, 19% to 57%.

Google Social Search officially rolled out Monday. People can test it in Google Labs, a section offering experimental search functions and other features.

Google pulls publicly available Web content from a person's social circle through blog posts, status updates, tweets and pictures. The set of connections, or social circle, provides the network. Google says it's using a normal ranking algorithm to pick the content.

Recently a social media analytics company, Sysomo Inc. analyzed information disclosed on 11.5 million Twitter accounts. This is one of the first reports to provide the depth of insight of how people are using Twitter. It also provides information on the most active members of the Twitter community. For instance, a small group of Twitter users account for the bulk of activity. Sysomos discovered that 5% of users account for 75% of all activity, 10% account for 86% of activity, and the top 30% account for 97.4%.
