Click the link that says "Psst, want me to love you? Then check this out "

I mean in a general sense. I'd pay for all sorts of things I currently get for free — writing, art, software, videos — if it was as easy as clicking a button. Getting out my wallet, entering a credit card number, and going through the payment steps is too much work for a quarter.

This is what http://flattr.com was meant to solve. Gratipay and Patreon also work but I'm allergic to recurring billing.
