How much is a twitter account worth?

Today, I stumbled across someone trying to sell their Twitter account for $300.

I was on Twitter, culling out some of the more useless people that I was following on Twitter. Mainly because I hit one of Twitter's limits on following people, so I was removing some of the people who never actually tweet.

Anyways, this person has 28,197 followers, and is following 29,768 people. They are listed on 126 lists. They have made 428 tweets, though their last tweet was on July 12th.

But is this Tweeter account worth three hundred dollars?

Beats me. I know that it is out of my price range at the moment. And it probably would be worthless to me; after all, I am dealing with a specialized market. The account was definitely not rigged for my market.

Yet, I still wonder if the account is worth three hundred dollars to someone who is less focused on a specific market than I am. Who knows. Nevertheless, I found it interesting---don't you?
