Nope. Both because people who don't write tech were invited and because I'm a tech writer who was not. Like you, I hit two of the $500's, so maybe that's it: maybe you needed to hit them all. Or maybe longevity counts. Or something else or a pile of elses.

I'm not going to fret. I'm enjoying myself and don't care about $200 a month. I might make $80 this month and that's fine. It's enough for the effort I put in to it.
