Okay, now that you've visited some, are you ready to comment? Contribute? We're ready ...
Do you have the list of the parties?

[eds.' note: SOMEONE has a list to the parties, and that person might become veeeeery popular, if s/he would share this with everyone, say, by posting it in the comments. We're already cruising the horsdooverays at the OMT shindig.]

You can access the online program </a< at http://program.aomonline.org/2009/ and search for "social event" in a particular division of interest, to find parties and such that are in your area of interest.
But there are the semi-secret lists compiled of the other parties. Usually they are the ones hosted by schools looking to build reputation. I have seen them, and gone to some of those events where being part of AOM is sufficient to get in, but not sufficient to be in the know.
I suspect it is a function of core-periphery structure in the acquaintance and friendship network.
