When looking for a link to give to someone new to the site about what kind of answers we look for I noticed the FAQ talks a lot about how to ask good questions but not about good answers.
Kind of a strange omission since it's actually good answers that folks are after. Even stranger that it took me 18 months to notice!
I wonder if it would be useful to have a series of before and after examples to show. For example:
Q: Where can i find Yak migration data?
Poor A: Yakyaka.com has a ton of great data, have you tried there?
Better A: Yakyaka.com has an archive going back to 1764, though the period from 1812-1855 is a bit sketchy. For quick overview of the holdings see the [online map viewer] and the raw .csv and shapefiles are on their [ftp site]. Note the data is free but commercial use requires permission (usually easily granted).
