Here's a few of the newer personal finance blogs I have discovered recently:
I may be getting too old to count as a "young" professional... but most of the information on this site is pretty general personal finance actually, rather than anything specific to young professionals.
This site's "Crazy Broke Item of the Week" should be a fun ongoing feature. I'm going to pick up some Gucci baby shoes when I buy my ice cube trays.
Nicole is another Brooklynite, and she tracks her daily spending on her blog, with commentary and anecdotes. And she's another member of the green template club!
I like this site because my cholesterol is over 200 too! But there are also some interesting, in-depth posts here. The Miserly Bastard is another New Yorker.
