I think it’s definitely worth a short blog post. When I signed in for plurk a few days ago, I was kind of disappointed by the user interface and found it a bit childish that you have to earn karma to get new smileys and stuff. However, I needed to know what it was about, because quite a few people came to my viewer project’s web site through plurk.
Now, a few days later, I have to admit that it kinda rocks, really. Once you friend a couple of people, it’s becoming an unstoppable phenomenon. More and more people get connected, and all of a sudden you have a lot of friends, and more importantly: fun!
You definitely should check it out! So many people from Second Life there!
