I agree with the thinking behind opting for a name that skews toward the professional and academic sounding.
But the current name is really not very StackExchange-ish. At least, not in the way of the older, original sites. Those sites tend to use a name that focuses on some term or phenomenon that will be recognized by "insiders" of the profession. E.g. StackOverflow, ServerFault, SuperUser, AskDifferent. Those are my favorite site names, and I think they are ultimately more appealing than a flat descriptive name.
So, my suggestion along those lines:
I think it's sufficiently professional to not draw folks Googling for pr0n, and sufficiently intriguing to represent a field that does, after all, deal with excitation.
