Also see Top Ten Design Mistakes. My biggest pet peeves: 1) Blogs with no “About” section. You don’t have to write a multi-page bio, just tell us something about yourself, even if blogging anonymously. 2) Difficult-to-find or no e-mail address.
Did you know that 6.4 billion people are blogless? Oh, the humanity!
Update (10/19): I hope no one thinks I’m calling them out with my pet peeves. LBC has some design and usability faux pas, too. As far as design is concerned, I prefer a less busy-looking, more streamlined blog, for instance, but I accept ads, which tend to look flashy. Between the minimalist look I want and ad revenue I need, I chose revenue. Bottom-line: design your site to your specifications.
