This is an excellent example of a top notch computer user group.  Check out The Boston Linux & Unix User Group.  They have several email lists and meet once a month in or around MIT.  The members are diverse and you would be surprised at the talent lurking.

I have enjoyed their “discuss” list for many years.  It’s friendly to GNU/Linux, BSD, and Unix noobs as well as useful for the seasoned professional.

They also have an interesting history.  Here’s a quote from their about us page:

Boston Linux & Unix began as The Boston Computer Society‘s Linux & Unix User Group; we’ve been meeting since 1994.

Whether you’re in Hawaii and want some nice folks to email with or in Boston and want to have a beer and chat in person, BLU is a great tech group for everybody.

I can not recommend it more.
