I know Good Math, Bad Math. And of course there’s this blog. And there are many other small math blogs – Integrating the Derivative, Polymath, Halfway There, ChapterZero, Exponential Curve, Kitchen Table Math, and Casting Out Nines, to name a few. I’m not sure if Not Even Wrong is a math blog or a physics blog.
But I don’t know of any really big math blogs except Good Math, Bad Math. If anyone knows any, please do tell me about them… I’m always looking for good mathematical conversations.
Abstract Nonsense 
Here’s one I can think of off the top of my head:

I know about that one (in fact, I used to comment on it). I didn’t list it because Moebius Stripper hasn’t updated it in months.
How about Rosenhouses’ blog?
Actually my blog doesn’t have anything to do with math. I just liked the name.
I’m not familiar with the blog you’re talking about, SLC. Can you give me a link?
http://www.scienceblogs.com/evolutionblog/
Don’;t let the evolutionblog identification fool you. Dr. Rosenhouse is an Assistant Professor of Mathematics at James Madison University in Harrisonburg, Va.
Thanks for the link, first of all. Second of all, there aren’t a lot of blogs about mathematics itself out there that one would consider “big”. However, there are a lot of “big” blogs that talk about mathematics education to some extent. Go over to Education Wonks and check out their blogroll. (Or go to my blogroll — most of the “Education” blogs listed are actually by math educators.)
Let’s see…. Talldarkandmysterious has , alas, more or less died. When it comes to nice (not necessarily big however) blogs, I have, however, apart from my own (shamelessblogwhoring)

[…] of EvolutionBlog is looking for math blogs. Many of the blogs listed appeared in my old “Where are all the math blogs?” post, but some don’t – Growth Rate n lg n, The n-Category Café, Recursivity, and […]
I’ve recently put up a math blog that is trying to address math concepts that typically give students the most difficulties. My website is http://sk19math.blogspot.com .
Here’s a directory listing of some math blogs: http://blogs.botw.org/Science/Math/
Fields medallist Terry Tao keeps a blog at http://terrytao.wordpress.com/ . It’s very good indeed.
Hi.
This is a blog with math problems based centered around a central theme. Don’t take it too seriously, but it isn’t politically correct either. So, PLEASE don’t recommend it to K-12 students. The math involved ranges from algebra, to trigonometry, calculus, probability, to discrete mathematics. Basically, nothing higher than college sophomore level. It’s meant to be challenging but entertaining as well…if you have my sense of humor. 😉
I hope you enjoy.
Maybe you should include mine:

cheers!
Great collection.
