If you are aware of "sponsorpay" the following may be redundant.
To those impatient to advertize their projects I offer a possible solution, in the form of a web service known as "sponsorpay". I know hardly anything on this service, but I do know one perspective on it.
When I was playing around in the Free-to-play browser game "tiberium alliances" you can acquire in game cash (the stuff you normally would have to pay Real life money for) by clicking on some buttons (getting there is besides the point) which then leads you to a list of tasks such as setting up an account or watching a video which once preformed awards the performer some in game cash.
Now here comes the pragmatic part.
Piedoom you could have this forum (or whatever) appear on that list of tasks and require players to create an account here (or something) for them to receive in game cash which would then make people (preferably bronies) come here, to liven this place up (if you somehow feel that yourself, Neveda0, anonymous14z, and everybody else, were generating insufficient activity here for your tastes.)
Additionally you could take a look at a few suggestions on this thread if you want more ideas.
