Inspired by Adam Kinney's Microsoft Twitter list, here's my list Twitter list of regional user group leadership in the Mid-Atlantic.
This list is by no means exhaustive, I know there are more user groups and user group leaders on Twitter.
It's a first draft, so please don't feel offended if I've left you off this list.
So if you don't see yourself in this list send me a message on Twitter (@Tableteer) or contact me via my blog and I'll add you to this list.
UPDATE 2: I've moved this list to a Silverlight Control backed by XML file: all updates from now on will be here: http://www.franksworld.com/Silverlight/TwitterList/
UPDATE: Added two more leaders and made a correction on another. Also, I originally thought of this as a DC, MD, DE and VA thing, but I'm beginning to see the need for a wider scope.
