List of mathematics-related blogs by academics

Note also just how many refer to Terence Tao's web pages... there is excellent stuff there.

Yes, he seems very prolific. He has these 3 pages listed:

Mathematics in Australia - Phil Broadbridge, Peter Hall, Birgit Loch, Terence Tao http://austmaths.wordpress.com/

What's New - Terence Tao (UCLA) http://terrytao.wordpress.com/category/mathematics/mathit/

The polymath blog - Tim Gowers, Gil Kalai, Michael Nielsen, Terence Tao http://polymathprojects.org/

I'm sorry, I don't even know what half of those subjects even involve. Perhaps a better list would be of links to /learn/ at least introductions to those different subjects. And Wikipedia doesn't count.

Your ignorance is not the poster's problem. I have a very general idea of what most of them are about. If you want to learn a bit ABOUT math it really isn't that hard, there are lots of good books, I suggest Davis and Hersh's "The Mathematical Experience" and Eric T Bell's "Mathematics: Queen and Servant of Science" to start. The problem with the Web is that most pieces are too short (for good reason, given the constraints) or too technical for basic learning.
