I’m a big fan of Plurk. It allows me to mircoblog and create a community, but more importantly, it lets me easily follow the threads of conversation.
The nice part about Plurk is that you can customize the CSS (Cascading Style Sheets) to give your page a custom, one-of-a-kin look. Here’s the video and send me a note, or leave a comment so I can see what you did, ok? And add me as your friend, too.
