Allow comments and posts to be edited by other users, with restrictions, as in Stack Exchange. Build the expectation that this is used strictly to repair formatting and improve linking. It bugs me when someone posts malformed hyperlinks and they're there forever because the original poster doesn't fix them.
At least, allow people to post "Community Wiki" posts.
In the next month, the administrators of Less Wrong are going to sit down with a professional designer to tweak the site design. But before they do, now is your chance to make suggestions that will guide their redesign efforts.
How can we improve the Less Wrong user experience? What features aren’t working? What features don’t exist? What would you change about the layout, templates, images, navigation, comment nesting, post/comment editing, side-bars, RSS feeds, color schemes, etc? Do you have specific CSS or HTML changes you'd make to improve load time, SEO, or other valuable metrics?
The rules for this thread are:
BUT DON’T JUMP TO THE COMMENTS JUST YET: Take a few minutes to collect your thoughts and write down your own ideas before reading others’ suggestions. Less contamination = more unique ideas + better feature coverage!
Thanks for your help!
