Twitter portals for non-profits, higher ed, SMB's

Heather at Diosa Communications has started Twitter profiles to act as portals for Nonprofit Organizations, Higher Education, and Small Businesses:

twitter.com/nonprofitorgs
twitter.com/higheredu
twitter.com/smbusinesses

Check 'em out and follow, if you are one of these. If you're looking to see who's on Twitter in these categories, checking out the lists of followers is a good place as any to start. Remember you can hover over each person's handle to get the scoop on who they are, assuming they filled out their profile description.
