comment centrally symmetric neighborly polytopes.
The question is not clear. What do you assume on Q? is it a convex hull of some vertices of P?

comment How to resolve a disagreement about a mathematical proof?
Umbra, it can be useful if you tell us how things developed. (Again in general terms.)

comment Interesting result on the Euler-Maschroni constant - what is the background?
The following blog post on Euler's constant on Lipton-Regan's blog rjlipton.wordpress.com/2013/09/05/eulers-constants featuring this paper of Jeff Lagarias arxiv.org/abs/1303.1856 might be of some relevance.

comment Ultrafilter-based Fourier-Walsh-like Functions
Dear Bjørn, The "General question" applies also to the first part and it will be very interesting to find nice applications for the W_Gs and W_Fs. (Of course, even if separated into two we can add this general question to both parts.) Maybe it will be easiest if you simply answer also the second part :).

comment Examples of major theorems with very hard proofs that have NOT dramatically improved over time
One way to regard this question is as a wish list: "A hard major theorem I would like to be simplified!"

comment Examples of major theorems with very hard proofs that have NOT dramatically improved over time
I vaguely remember that Deligne's proof and some new approaches/simplifications were discussed, but maybe it was in a different question. It is certainly a good answer!
