Web communities are occasional stop-bys for most users, but a listserv community like Progressive Exchange lives in your inbox. It's a regular presence and a good resource, as long as you're not one of those crazies who's compelled to read every single message.

Progressive Exchange is worth the extra mail: a network of NPO tech staff, consultants, strategists and vendors more focused on problem-solving than self-promotion (though there's certainly some of the latter).

Topics range from one-off announcements of jobs, seminars, and semi-formal gatherings (mostly in D.C.), to calls for referrals, to roundtable discussions of news and innovations, some of these becoming pretty serious group analysis.
