It's just as easy to overlook the blog link though. Plus this blog actually is practical and relevant to the forum and grad students in general. It seems to me that gradcafe has such a solid community of support and advice, and folks are just trying to spread the little nuggets of wisdom and advice that they can give. Who is to argue with that?
Also, I'm just sayin, but almost all of the links Fuzzy cited started off by introducing a link to another site...that does not seem really different than linking to a blog and could easily be seen as a form of promotion for any of those sites. So long as it enriches the forum, I am down.
