This is a very interesting use case, particularly in investment analysis, my area of specialty.
The problem of obscure, rarely updated blogs with fantastic information (but no reader base) is plainly evident here. I can think of a blogger who is a fixture on "who's who" lists, but publishes a blog so ill-trafficked you can hear the crickets chirping. There are hundreds of these guys.
I'm at work on a finance-specific version of this. Hopefully we can announce something before the readerpocalypse.
