I've been here around a week and here are my impressions.

• The site is fairly usable, but can be a little slow at times. Some features do not appear to work, e.g. I get messages about my progress that I am supposed to be able to post, but these always fail to save
• I've gained 2 referrals so far. Neither of these is very active and so not making me much
• I've made about 18000 satoshi. Not a great return so far
• I've gained a load of subscribers, but they do not interact with me
• Most of the posts I see are about Judo. Not that interesting to me. Second to that are some little animations. Also not too interesting
• I've grabbed a few free items to clothe my avatar. Yeah, wow ;)
• All I can see to do here to boost my buzz is to view a few posts and videos. I think the 3 types of currency are confusing
• Until I have some actual friends here I don't do much. I may just post the occasional cool link
