Joshua Marshall shares an account of the start of Talking Points Memo on Alternet. I run hot and cold about the site, but it’s certainly one of the best resources online for understanding political news. One thing I have wondered about is its expansion from a blog to a broader political news site, which Marshall says was necessary in order to get the ad revenue to support a news operation.
