I have some friends on Twitter, a couple on Pownce and Jaiku is the platform of choice in the swedish tech sector so I am getting into Jaiku as well (I am “andreaskrohn” on all of them). Which platform you use depends on what technology you prefer and where your friends are. I don’t really care about the technology at the moment, I just want to keep in touch with my friends (yes I know that Pownce API kicks Twitters ass and that Twitter goes down more than an intern in the Clinton White House, but believe it or not, I prioritise friends over tech). These are 3 different platforms, each trying to be a community. But the community of any one person will not live on one platform, unless that platform gets to be either completely dominant or the technical platform providers takes a step back and let the community live across providers. The latter has happened with telephone services (you can call friends with a different cell phone provider) with email (i can mail people that are stuck on Microsoft Exchange from my Gmail) etc etc. I can not wait until this happens to the microblogs!
It is quite easy to post to several microbloggins services at once. Jaiku does a great job of importing RSS feeds, so posts to Twitter or Pownce can easily be imported to Jaiku. Via Twitterfeed it is easy to get an RSS feed into your Twitter as well. I haven’t found any easy way of getting an RSS feed into Pownce. Also there are apps like Twhirl that let’s you post to all 3 platforms at once. In my case I also use the Twitter Facebook app to get my tweets into my Facebook status and I am looking for a way to do the same with LinkedIn (no success yet). So posting cross-platform is not a problem, even if it means that you need to do some configuration and that all your posts gets trippled or quadrupled.
Reading friends posts from several platforms could also easily be done. I could of course go to all the different services and read each posts on each one, but since I want to do other things with my day than that I would rather use services like FriendFeed or SocialThing that aggregates it all into one place. FriendFeed imports from most sources and have some nice comment features, but the UI really desperatly needs a designers touch. SocialThing imports from just a few places so far (please please add RSS now!) but I still prefer it to FriendFeed. These services and others make it easy to see your friends posts from several platforms in one place. What is missing is a way to naturally post back to the microblogging platforms from these services.
What is needed, and what will come very soon I am sure, is a mashup of all these microbloggin platforms to allow users to be active on several platforms at once all from one place. I would like to see an app that allows me to interact with Twitter, Pownce and Jaiku completely. This means reading other peoples posts, replying to posts to have a conversation going cross-platform and posting to all platforms at once. Since all of the platforms have APIs this should be possible to implement (and for all I know it already exists somewhere, if you know of such an app please let me know through a comment on this post!). This would be a great mashup that would breach the community silos that exists today. Short of everyone moving to one platform a mashup is the best answer to this problem.
Btw, I have some extra SocialThing invites so if anybody wants one please let me know via a comment on this post.
