Identi.ca sets itself apart from the all the other microblogs by being totally open source in all things in that it is actually powered by Laconica.
I am not sure if this one will compete with the others in the long run, but I think that is okay. I think we may all benefit from having this around in the long run.
Everyone should sign up for a Rejaw account, just because it is so darn easy as you can see by reading An OpenID-powered registration system I actually like…. That part is awesome.
What isn’t that cool to me is the lack of any sort of web feed. I always like to send my be able to move my posts to a microblog out to the various lifestreaming services. Not being able to do that is not going to make me want to use the site more.
I got an invitation to try out a new microblogging site this morning. I actually wasn’t sure quite how the site worked until after I completed the signup process.
I think it has something going for it among big gchat and yahoo! chat users… but I am not either. The ability to pull in friends from twitter was a nice feature, though; that instantly gave me some to work with.
