I recently had a friend turn me onto another micro-blogging/status Web 2.0 application I've been having a lot of fun with called Plurk. It is kinda like Twitter (if your familiar with that) except it is all done on a timeline - so it gives a unique view of things. Also has things such as inline comments, better design and a lot of other little quirks about it that are just nice.
Can't promise too much LP content there, but your free to join me as I play with it:http://plurk.com/redeemByURL?from_uid=2381995&check=-564125811&s=1
I usually have a bad habit of joining everything, but as long as they keep the service up, I think Plurk is a new regular stop for me on the Web.
