While you should avoid tricking visitors with artificial numbers, this video does give an hint that FeedBurner numbers are very easy to manipulate.

Joop shares a simple hack that will enable anyone to artificially inflate the FeedBurner subscriber count of any RSS feed that’s syndicated via FeedBurner.
