William Parke at UNC has just started a Finance Roundtable. He's been running the Econonomics RoundTable for some time, and has expanded the Roundtable concept - he now has separate roundtables for Econ, Finance, Law, and Politics. Each Roundtable aggregates new postings from a number of blogs in the subject area, and puts all posts for the previous 24 hours on one page. they're excellent resources.
For the main page, click here. Nicely done.
