So the Community user bumps posts occasionally:
Posts eligible for bumping are those scoring >= 0 that have gone at least 30 days with no activity, have at least one non-deleted answer scoring 0 and none scoring more than that, and no accepted answer (also, they can't be deleted or closed).
The problem I've been finding lately on Hardware Recommendations is that more often than not, this just results in bumping old crap. It selects questions that just about meet the requirements for topicality and specificity, but aren't well-written, aren't interesting, and aren't examples of good content that we should be continually pushing to the top of the front page.
I'd dearly love the ability to have this either turned off completely, or to have the thresholds tuned - even just adjusting the score threshold to >= 1 rather than >= 0 would have a significant impact on a site so small. I'd also adjust the minimum age to more recent (say 14 days), add a maximum age of around six months so it's not bringing up ancient, long-dead recommendations that make no sense with current hardware, and require that the answer score at least 1 as well to avoid promoting minimum-effort answers.
