Bloggers in Philly need $300 license

Marilyn Press of Philadelphia operates a blog called msphillyorganic on wordpress. Her blog is a hobby and she feels she may have earned a grand total of $50 from it over the course of the last several years. The problem is in Philadelphia there is a law stating if it has the potential to make money she must have a business privilege license at a cost of $300. If that were me I would start a new blog called Why Philly Stinks and make sure I got my money's worth. Really ? We give tax breaks to giant corporations to do business in our cities, but we need to license bloggers. Hopefully some of the more successful bloggers can chip in and pay for her license.
