I had never heard of Guster before I saw you open for Dispatch a number of years ago. It remains the only time I've ever gone to a show and left as a bigger fan of the opening act than the headliner! I'll also always remember Ryan (I think?) on stage saying that if people didn't buy his shirt that said "Fuck you, penguin" they'd never let him design a shirt again. Did he end up losing his shirt-design privileges? I'm hoping not.

I'm toying with the idea creating a web app that would use OSM data that I'd have to download from geofabrik or a similar source, and presumably update semi-regularly. What's the best way for someone using OSM data to be a good citizen and give back to the people you're downloading data from?

I'm particularly interested in data for particular buildings / addresses, which is sometimes sparse in my area. I'm reluctant to contribute personally because I'm not sure I understand the expectation of accuracy - I can't exactly provide GPS measured coordinates for corners of buildings, especially for conjoined addresses. How do I know if my data is "good enough?"
