I’ll answer just about anybody’s question for free. Then I’ll post the question and answer on the blog (after checking that it’s ok with you). Since I’ve done it for free, my answer is open-source, and I’d like to share it with as many people who might be interested. I also work on projects that are publicly funded, or help people who are working on such projects. Again, your tax dollars already paid for this, so I’ll post on the blog as appropriate. Finally, sometimes I’ll consult for money, in which case you can tell me if you don’t want me to immediately spread our findings to the world in this way.
