The Atlantic, back from the dead thanks to years of Bush, has added blogs. Fallows has a new home. (Shame on losing the quaint first posts in his "test" blog.)
There are blogs for Sullivan, Fallows, Douthat and Yeglesias so far.
Update: There's something funny with bloglines and this feed. The subscription seems right, but no postes appear. I can't say whether the bug is in the feed or in bloglines.
