Since I got my new computer, Michael is trying to teach me some of the new things in techie world that have been created in the past six years when I went underground to have kids --and apparently lost touch with the outside world.

My latest discovery is Plurk. I am still trying to figure out what Twitter is all about. Both appear to be social networks and now I am torn because I know Twitter is more popular than Plurk. But I like Plurk better. So, now what am I supposed to do?

What is the coolest thing you have discovered online lately?
