I don’t think there’s any reasonable way, or any need, to separate vanity and ego from a personal blog. Writing is inherently about its author, and is a product of their personality and opinions – that’s not something to be shy about, and we shouldn’t try to change it either. So, write for yourself – and hold yourself to an appropriate standard, because you’d better believe that others are judging the person as well as the piece – but as soon as you publish your views, you’re inviting readers to take a look. I think that the needs of the reader and the author are more aligned than many blogging systems seem to believe.
Having had a decade to think about it, I want to share my views on what I think you do and don’t need on a blog today. Your needs may be different, but perhaps you’ll find something to think about. I bet you could simplify your blog in some way without detracting from the reading experience.
Matt Gemmell has some wonderful suggestions for offering a better reading experience for your audience. I think he’d approve of most of the design decisions that have been made for this site.
