This is pretty ridiculous, although with the budget issues that so many cities and counties are facing, I guess it's the sort of desperation play one should expect:

She’s not alone. After dutifully reporting even the smallest profits on their tax filings this year, a number — though no one knows exactly what that number is — of Philadelphia bloggers were dispatched letters informing them that they owe $300 for a privilege license, plus taxes on any profits they made.

So, what the heck is a "privilege license", and why the heck would a blogger making pennies from AdSense need one?
