Similar online groups for surrounding communities?

So, I love DSLJ, but what are similar online groups to Davis_Square but for other towns around Boston?

I know about b0st0n on LJ, of course, and /r/boston on reddit. There's the Porter Square Neighborhood association mailing list, which is largely development focused. 

And so far I've found these:

Newton Parents

Arlington List

Lexington List
JP Moms

Ron told me about Medford List.  Know of any others? Weston? Wellesley? Quincy
