From @jdlasica via @briansolis and @daniellemorrill, here’s a compilation of 2009 social media events around the U.S.  I’m fairly surprised that there are no international events listed.

In perusing this list, I was also directed to this list of 2009 tech events compiled by Robert Scoble.  This list is broader in scope than just social media events but doesn’t look as far into the future.
