Possibly @MartinSleziak. There was a time when the HNQs from Math.SE were not exactly interesting. I guess the situation improved after moderators were given the power to remove entries to HNQ. I simply haven't looked at them lately, so I don't know.

@Sil voila

We remove PSQs and generally unexceptional questions from HNQ, which unfortunately is most of them. For technical reasons, HNQ won't be selected if they have tex in the title, which leaves a pretty small pool for the algorithm to pick from. I think that's why ours tend to be crappy.

It might be fun to have a weekly or biweekly or monthly digest in here of questions that get an answer from being posted here, and/or list of unsolved bounties.
