Just to start things off then:
in reply to Upcoming survey to help me better the site
Overall organization - are all the divisions of the site clear and useful?
Searching - how hard is it to find what you are looking for?
General Interaction - how do you like the entering of text, code, links, etc.?
Chatterbox - what other commands would be useful?
Documentation - is everything about the site sufficiently well explained?
I'm probably forgetting a number of things, but these were on the top
of my mind.
