After browsing the links you've provided, here are my thoughts on this:
The NU Ubuntu Team's Launchpad site lists several goals, all of which I think are consistent with Ubuntu's goals worldwide and our local goals here in Maryland.
I am a little confused about why Maryland is clumped into the Northeast region when the Census Bureau claims otherwise. This may present a few problems in the future. For example, any regional meetings will be larger and potentially farther away. If there were a mid-Atlantic regional group, I'd prefer to join it for the sole purpose that I'd be more able to make any regional gatherings or events. Not to mention that I think our mid-Atlantic groups will work better with our neighbors if our leadership were closer to home. However, as no such group yet exists (maybe Maryland will take the lead in starting one?), joining the Northeast group seems to be in the spirit of cooperation that Ubuntu stands for.
Finally, as Ubuntu continues to grow, I think we need to stick together despite any minor differences in philosophy. I don't want to make it sound like we're William Wallace fighting the English, but Ubuntu is up against some serious odds, and we can use all of the support and help we can get.
