I just sign up for a Twitter account. The idea is simple. Inform your friends about what you’re doing in short sentences. Kind of a mini-blog. I think it can be useful to make annotations and then revise them some time later. You can put links, share ideas… Of course, to work properly, you should update quite frequently.
I tried to add a JS in the sidebar, but that feature is not activated. And the updates via IM don’t work either. :’-(
Let’s try one more time! BTW, anyone wanna join as a friend?
Update! WP doesn’t let you include JS, but I just discovered you can use an RSS feed. Now I have news displayed on the top right corner. Happy happy! ;D
