Hire people to post at the beginning. Offer cash prizes, say $10 via neteller, for someone randomly drawn from the day’s posters. I would think that might help get some action. as the daily posts increase, switch from $10 a day to $50 once a week, then $100 once a month. As you move from daily prizes to monthly, make the prize for “best article”, where you pick 5 posts and have the community vote on the winner.
that’s one specific, simple way of trying to build traffic, for $300 or less a month.
