pauloaguia: Or instead of every week, whenever there is a "dull" time. For example, lets say you notice that a week went by without a post, maybe introduce some "quickie" questions for people to answer. Maybe even like "poll" questions like what new game would you like to see on this site. (with a list of some options with of course leaving it open for any answers).
Seasonal questions like "Did Santa bring you anything this year?"
Yea, a threaded board would make it a lot easier - but maybe an idea to keep when the posts do slow down - and randomly so you are not forced into doing new questions weekly and such.
