Tim Bray
While my own weblog clearly leaves a lot to be decided, I can take the opportunity to comment on Tim Bray's ongoing, the very clear winner in my own personal contest for Best Weblog of the Month. Tim's thoughts do not always concern topics that I'm interested in, and I don't really like the design ... but what clearly differentiates his from most other blogs is that his style of writing is just great, and that there is not a single posting that does not immediately show how much care he took in writing it. So if you regularly read blogs, make sure to include his RSS feed.
