This is identical to my misplaced "answer" here, written while attending JMM. I am reposting a fresh question at François G. Dorais's request.

I wonder if it make sense, at some future Joint Mathematics Meetings (JMM), to have a MathOverflow booth among the "Exhibitors"? Not all booths are publishers. For example, the Online Encyclopedia of Integer Sequences has a booth at JMM , as does the Museum of Mathematics. I know nothing of the financial aspects of this, but it certainly would raise MO's visibility in the U.S. Of course, this assumes that raising MO's visibility is desirable.

One could ask the same question for equivalent broad math conferences worldwide.
