The state of Pennsylvania tourism office has created blogs for people to record their visits Pennsylvania attractions this summer. In exchange, the "bloggers" get an all expenses-paid trip.
In my opinion, this is a great use a blogs. When I plan a vacation, I often scour the web for reviews of hotels, attractions etc. in the course of planning my trip. First-hand, real-world experience is invaluable.
