The first time I activated my account was to send money to Vimcasts, which I'll probably do monthly now that it's set up. If I find nothing else flattrable (I'm picky with my money), they'll get a decent amount of money out of me, and I'll call it worthwhile.

Vimcasts is so good, I likely would have done the same, if I hadn't just donated via PayPal.

This is exactly what made me put money on my account, actually.
