I'd like to nominate this post by @c0ffa33a because he put an awful lot of work into his blog for a contest only to find it was too late to be accepted. But that didn't stop him, he submitted it with a positive attitude and because he likes to make people happy with his posts. I was also very impressed with his macro shots.
