Developer donations

Pledgie I just made my second donation this week to open source software developers who build/maintain projects I'm using. It feels good. I like pledgie.com and the fact everyone seems to be using it because I can see what I've donated and when. I like the ability to give for the value I'm getting and to give more as I get more value. Isn't that how it's supposed to work? Taking without giving isn't healthy ... ever.
