[quote="deadeye":2z5z2c5q][quote="Azu":2z5z2c5q]So you can choose what to pay for huh. That's...kind of weird.[/quote:2z5z2c5q]
There have been a few instances of the pay-what-you-want model, including albums from Radiohead and NIN, as well as the Humble Indie Bundles of popular indie games. It's just another way to combat piracy and still make a little money... pirates often cite "too expensive" as a reason to steal stuff, so this sort of removes that excuse. People who think $20 is too expensive could chip in $5, or at least $1. Or really at least $0 I guess, if you think that's all that it's worth to you.
I think there's another big advantage. People earn different. So if you sell your software for 50$ it might be 1% for the one making 5000$ a week, but 50% for the one making 100$. If the last one now spends 1$, it isn't much money but the same contribution in relation. Should motivate a lot more people. At least I hope so.
