At RSA, I was made aware of the Security Catalyst blog. And though I had heard of them before, I hadn't ever spent any time reading the blog. It has quickly gone to the top of my reading list for security blogs.
One thing to check out is that they've just announced the Security Catalyst Community, which is a new place for security people and those interested in security to talk about interesting topics.
I'm excited to be a member and to debate security topics on the forums over there... it's worth checking out.
