So its not just me who is on more than one social network......Nielsen's survey of UK netpeople (
see here) suggests strong overlaps in user bases. Don't you just love the Facebook / MySpace commonality.
Implication.....that the market for social networks is becoming like that for fizzy drinks or fast food...most of us use most of them, there is little of unique value except the buddy list - but it is clear that we do move 'em over, its no real barrier to exit.
And therein lies the seeds of their destruction....its a pain to port my buddylist from say Linked In to Facebook, the easiest is just to get everyone's email and...wait a minute...if I have everyone's email why bother with a SocNet, as its far easier to communicate from an email client than the multiple skips and clicks in the average SocNet.
Also, its seems that they are
not such great cop as Ad servers, and that ultimately will determine their fates as people by and large have not been prepared to pay for SocNets in Web 0 or Web 1.0...and the newest darling, Facebook,
seems worse than others
Maybe Microsoft Outlook is the ultimate Social Network....
