What do you think about Formspring ?

My friend was talking about this new service (I understand that you can ask and answer others people questions) but I don't know very well. I was reading about this site and discovered that his launch was 3 month ago. There are many bugs still didn't receive fixes. Then I want know if somebody (that already use) can let your opinion.
