Great feedback.

-GPX support is top of my list of TODOs.

-I like the USGS topo / OSM idea. I'll have to do some investigation to see how it compares with Google Maps.

- I agree that a bibliography is a must. This is also something I would have gotten for free with MediaWiki. The reason I didn't build on top of that was, basically because I wanted to have complete control over the end result. Writing the code was the fun part for me. That being said, I wouldn't completely write it off.

- And I did write one scraper already for wta.org, but was unsure about whether that was ok to do or not...
