My biggest problem with the question is that it isn't terribly related to physics as theoretical physicists practice it, but rather as mathematicians practice it. Hence, I voted to close, but that was also at a time when there were a reasonable number of people holding the same opinion. I then went idle for a few days, and missed the discussion. In a sense, my complaint is the same as in Scope and FAQ - for researchers in theoretical physics and related fields.

I don't think I would still vote to close it, but I also don't think it's a very good question at this stage. Based on the current population of this site, it seems vulnerable to being taken over by mathematical physicists and mathematicians, leaving out a rather large portion of theoretical physics. I'm interested in mathematical physics myself, but I don't want this site to be only for that, because it has the potential to be much broader in impact (and such questions could already probably be asked on MO).

Now that the question has been reopened, I don't really intend to try to close it again (at least for the time being), and I'm considering composing an answer. That being said, I think the distinction between mathematical and theoretical physics, in the context of this site, needs to be drawn. Piotr's proposal to remove preference for mathematical physics has +7/-0 vote right now, which seems to be fairly strong support considering the traffic on meta. The naive way I am making the distinction right now is that theoretical physics is practised by physicists, and mathematical physics by mathematicians. However, this is certainly not the only way to do it, and probably not the best way.

If I had to state my criteria clearly for questions, I'm fine with hard questions on mathematical physics, because they should be inherently of interest to theoretical physicists. For soft questions, I'm quite a bit more critical, and I think it really has to be something that the average theoretical physicist (perhaps in a particular discipline or sub-discipline) would be interested in. I'm on the fence for this particular question, but as I said before I don't intend to try to close it.
