I was thinking about this some last night on my way home (hey a two hour commute gives you a lot of time to think)….and I think I decided that all of this social media works best when its interconnected.
They key to any of these sites being successful is their ability to talk to one another–not their ability to get me to set up an account on the site. I have friends on Facebook, Twitter, Plurk, Jaiku, FriendFeed, BrightKite, MySpace etc…some are cross overs and some are not.
A useful tool for me is one that allows me to reach all of them at once, or gives me the opportunity to do so.
So, in my case I use Ping to update Twitter, Plurk, Jaiku, Friend Feed and Jaiku. Friend Feed updates Facebook and Brite Kite.
So I have input once, and reached everyone-whether they wanted it or not (that is their problem).
So now the challenge is to aggregate all of the comments, replies and postings from my friends in one place. I think that is the next great spot to conquer–because reality it there are some sites (Friend Feed, Jaiku) that I just don't check. Not that I don't care about what is happening there, just their UI's are awful–and it takes too much work to figure out who is saying what-and if any of it is in response to me directly.
