I backed off from all the enthusiast sites I'm involved with due to classes and other things pre-occupying me for this year.
I've seen multiple park coverage on other sites and some hop while others flop. I'd recommend keeping it to parks where you have people who visit multiple times a year (not 3 or 4 times, in the neighborhood of multiple times a month) so that every park we potentially cover has most, if not all, news, events, and rumors covered. I've noticed what really gets people coming to the boards are constant and quality updates about construction and rumors, and getting them on Screamscape with direct links to the threads.
I'd love to add more but I got to get back to studying, finals start Friday!
