Absolutely go for it. We did a PM get-to-gether at the last PerlCon, just a bunch of Rowdies in the back of the bar singing Old Perl songs around 1830 on Tuesday night. We will do it again this year. (Note: putting on a conference is hard work. As part of the Con Committee, you do _not_ have time to do any of the fun bits. As a BOF organizer in someone else's Con, you actually will get to attend your event.)
