Nice thread, it's great to see things like this posted up. But I gotta say it's different for every situation. Yeah, you can create a forum about your own interests if that's what you're passionate about. You need passion to maintain interest. But at the same time you gotta draw the line between what you think is good and what others do, the "public" are your customers. If you're in it for the long haul you've gotta be prepared to go the full distance. At some stage that may mean stepping back from your board to focus on getting your servers optimized better. Faster pages = happier members. There's just so many aspects beyond actually posting that you need to think about. Are you happy to take a financial loss initially to please your member base? Why are you in this?
I think the best thing you can do is get a couple of your good friends along and post a bit. In my opinion the hardest part is starting the movement, once it's started it's kind of hard to stop. But you need to know how to manage that rolling snowball otherwise you're gonna end up with an avalanche, big and furious but fast to die.
This is a great video to watch BTW "How to start a movement": http://www.ted.com/t...a_movement.html
You have to embrace those around you first.
