maybe because you don't have many responses to yr posts, ou because you dont have many friends

When you post often and get replies it raises, inactivity lowers it. I hope this helps

What happened this weekend? I heard you had trouble getting a yorkie

that parishilton is asking other people about "going down"

you probably have to response to other posts more often

my plurk goes down if I dont log in enuff, which is cool, i guess
