Stickying topics in many forums actually decreases the amount of views it gets. This depends on different things like amount of other sticky threads in that forum, forum design, etc. Having an active topic that is bumped by people interested or kept up by staff is usually in better view and gets better noticed.
It was made pretty clear that the hard advertising would start once live was announced :)
@Karasu probably better to ask in the Citadel forums by PM or on the irc.
