Copyblogger is a blog for bloggers. (You knew it would come to this someday, didn't you?) More precisely, it's a blog that gives tips on writing for blogs in a way that helps you promote whatever it is you're promoting (your company, your products, yourself...whatever). This week they announced that they have again topped Writing White Paper's list of top 10 best blogs for writers. Check out the full list here.
Thanks to technical writer and freelance editor Mark Cierzniak for tipping me off to the existence of this blog.
