What do I look for in a blog?

It’s not often that I’ll add a new blog to my reading list, but when I do, I’m looking for interesting content, well written articles, an active community, the ability for readers to leave comments and bloggers who actually respond to their readers comments.

The following is a list of marketing blogs that I read almost daily.
