I’ll admit — from the moment the intro session started at BarCampMilwaukee, I was hooked. People throwing around names like WordPress, Joomla, Drupal, and Rich Internet Applications and I knew I was in good company. Granted I’m not very experienced in the last, but I can recognize the potential and am trying to grasp the concepts of Adobe’s AIR development platform.
The sessions I got the most out of were the ones I could use that day. My professional web site (you’re here, obviously) was stale and the WordPress session inspired me to tackle a redesign that made maintanence 100 x easier and posting 100000 x easier.
The second-most useful session was Drupal. I’ve never used Drupal to build a web app, but when I was trying to decide between CMS’s it was Joomla or Drupal. Armed with some new ammunition, I might do some more exploring of Drupal as a robust CMS that has solid code and some cool features that Joomla doesn’t offer.

We’ve got a good mix of local people who are into either WordPress or Drupal (and some use both…)
And it sounds like WordCamp and DrupalCampWI2 are being planned for 2009 in Milwaukee, which should both be really cool.
