Just how popular is Twitter?

Popular enough that the Council on Foundations is using the tool to provide updates this week from its conference in Atlanta.

The organization will be tweeting the conference on its Twitter page.

For those who are looking for news in more than 140 characters, the council is also running a conference blog.

And if you’re looking for more perspectives on the annual conference, the Chronicle columnist and blog writer Sean Stannard-Stockton has assembled a team of 12 volunteers to offer their accounts of the event on the site Tactical Philanthropy.
