Blogging is good for your career

Blogging is good for your career. But I wonder what sort of posts are seen as career-improving material? How to manage your boss might go down with prospective employers, but What to do when you find a wet pussy might not go down too well with the humour impaired. Then again, I hate working with dull people who never laugh. Humour is the only thing that can keep me sane when the shit hits the fan.
