I'm pretty sure you're all acquainted with Wikipedia. It's fun, sometimes exasperating, but certainly an interesting experiment. I've contributed to articles on the A.T., Benton MacKaye, Baxter Park, Gov. Baxter, Katahdin, and a few other topics.
I recently realized there was no Myron Avery article, so I've just started to write one:
http://en.wikipedia.org/wiki/Myron_Avery
Wanna help?
