Nice of you to say so but I don't think I've had much effect on usage. The greatest change has come from sites like lifehacker, or popular journalists starting to use the word hack.
Reading Hackers and Painters (the essay not the book) was the first time I'd realised that what I did had a name. I now take it for granted that other developers consider themselves hackers. I'd argue that the term filtering down to lifehacker and popular journalists is a consequence of that kind of mindset change. Which you have helped with.
