I uploaded what I think was the first tutorial on how to use Photoshop's then-new "Content-Aware Fill" to help create panoramas, and also a tutorial about...something, I forget what, to do with the music engraving software Sibelius. They were things I was doing all the time, but there didn't seem to be any guide on how to do it, so I thought I'd help out. And I got rewarded with a little cash and a few tens of thousands of views. Felt good.

There are much better, higher-polish videos that deal with those subjects now, I'm sure. But still, it didn't feel good getting that ripped out from under me, and being told I was no longer welcome.
