B2B Blogs to Watch

I can't say I've looked through every one of these recommended B2B marketing and strategy blogs, but the scope and depth of subject matter alone makes these good resource listings: Big List of B2B Marketing Blogs.

Over time, B2B Marketing Excellence will recommend other resources and listings and create our own list, the in-depth version we will host in our social networking community, B2B Expert's Forum, but in my opinion none of us will live long enough to justify recreating any wheels. Let's all ride the ones that work.

Anyone know of one that isn't in their listing? Comment with the url below and let them know as well.
