Blogging in 140 characters or less. I have mine linked up to my IM so it’s kinda like a public group IM. Then I have various RSS feeds that will also post a link to the twitter when I update it. I also can update Sandy with it by sending a direct message to the Sandy or Remember the Milk to add stuff to the lists. Also I can get to it from my iPhone which is very handy. And I forgot to mention that I have the last 10 posts on the sidebars of my blogs. Just in case anyone wanted to read there without signing up for twitter.
