NYU has one of the largest and best finance faculties around (most surveys place them squarely in the top 5 programs in terms of research output). It turns out that they now have a blog: Stern Finance.
It looks pretty promising. Although it's less than 2 months old (the first post was made on September 26), it already has a lot of high-quality content, with participation from a pretty large nuimnber of the faculty. Just this last month, it has posts by Viral Acharya, Marti Subramanyam, Edward Altman, and Joel Hasbrouk among others).
It's definitely one to add to your feed reader.
