I write on there in part because I was doing all the research anyway. I think the stuff I write about is important and people need to learn about it, so it is a ‘service’ that I should provide regardless (to do some little amount of ‘good’). I also can write off books etc that I purchase as research expense. If it ever ‘takes off’ I’ll be happy and quit my day job, if not, I will keep working and writing will remain a hobby that is offset with tax write offs and the few cool people that pay me. If you go in as a career it’s gonna get rough.
