I found a very cool idea for a web log: a weekly discussion of evolutionary science called This Week In Evolution.
Each week, a recent paper containing original data from a peer-reviewed journal will be discussed. Since there is a lot going on in this field, it is extremely useful to get a guided tour of the landscape based on actual data (as opposed to random books or web pages).
