We’d like to think that the links we share on social networks have a life of their own. However, the links we share on social networks have a half-life shorter than the North American mayfly.
While a mayfly can live for up to 24 hours, most of the energy behind the links you share on social networks is spent in a few hours. According to bitly.com, the leading site for shortening and sharing links, links shared from Twitter have a half life of 2.8 hours. This means that in less than three hours the link has gotten half of the click-thrus it will EVER get. The average link shared from Facebook has a half life of 3.2 hours. The longest-lived links are those shared from YouTube, which average a 7 hours half life. Bitly’s results were based on examining the half life of 1,000 popular links shared from Twitter, Facebook and YouTube.

When I get more text messages on my mobile phone from mobile spammers than my teenage daughter, something is wrong.

Social networking has been around for hundreds of years — well before the advent of Facebook, YouTube and wireless networks. It just used to happen face to face: over a cup of coffee.
