If one wants to make bounties more useful, then I think one should rather make them last until the question is answered in a satisfactory way, than trying to enforce bountied questions getting more attention. I think it is perfectly sufficient that bountied questions are visibly marked as such and can be searched for in some way -- the "featured" tab and any additional bumpings are completely unnecessary in my opinion.

Besides that, .com wouldn't fit already since MathOverflow is not a commercial site.

@ToddTrimble: What has happened here? -- The account merger hasn't taken place, but rather Erin's original account appears to have been deleted(?)

@YemonChoi: Yes, as far as I recall, before the move to SE 2.0, there was. -- And that close reason would appear more natural to me -- ideally accompanied with a notice that similar questions would nowadays likely not be welcomed in that way any more.

While I do not have a strong opinion on that question in this or that way, an "off-topic" closure after 113 answers looks weird.

My preference would be to get notifications for comments on answers to questions of mine. -- I mean, a comment may even point out that the answer is wrong -- and certainly I would want to know about this in that case.

I think outside the US, the Confederate flag is not that widely known. Many people would rather associate the Flag of the United States with all of the things you say the Confederate flag stands for, plus the deeds of the US Army in all of the wars and other war-like actions around the world it was (and is) involved in.
