This is more of a philosophical question for Gittip. I'd agree that the option for one-time tips makes sense. Maybe I periodically contribute to someone who periodically updates a personal wiki, or after a new release of a project I care about. I'm not sure why Gittip decided for subscription-only, but I'd agree that one-time tips make sense as well. If I had to choose only one model, I'd opt for one-time tips. But (crucially) I still think a quarter is way too small a floor. If I don't value the project enough to make a one-time contribution of even $1 (ideally more), wouldn't everyone be better off with me just sending a nice tweet and/or email? The quarter doesn't really help the developer much more than that. If I were mailing a shareware payment in the olden days, a quarter would barely cover postage.
