Ask YC: I have a twitter account with 1800+ followers, what do you think it is worth?

I'm just curious what the account may be worth. I've actually had the account less than a week and it has grown quickly. I remember there was some guy who was trying to sell his twitter account on ebay and the bidding was up to $1500+ (for 1500 followers) before he canceled it. I know it kind of depends on what the account name is, etc... But I'd prefer to remain anonymous right now and I am mostly interested in a generic $ value/follower figure. Any best guesses? Thanks!
