Every blogger loves to see high RSS subscription numbers, and a blog called Bob Meets World has put together a unique contest to encourage readers to sign up for his feed.

The 30th commenter will reveive $30 via PayPal, and the 100th commenter will win a free review of their blog and several backlinks.  The contest is over on the last day of June.
