I found google buzz today. It’s pretty neat. Definitely a rival to twitter, but it has no 140 char limit(which twitter does).
A couple of things I like:
It has a feed, sorta like facebook/twitter. Constantly updatable
Type in a link to an image, and it automatically inserts the image along with your comments fo ryou
Gmail keeps track of any “conversations” you are having in google buzz
Things I don’t like:
No Igoogle plugin
Google didn’t create a android app for it yet(WTF?!)
I doubt there is an iphone app yet
Overall my dislikes will be resolved(I assume) over the next few weeks at the most.
