This issue was indirectly addressed before by Emile, and commented on specifically in a reply to the previous by jwhendy. But it's probably an important enough usability problem to warrant its own top-level comment.
Currently the parent should have at least +6 extra upvotes going by that second link, possibly more, assuming the same people didn't upvote both. (I rescinded my vote from before, and I am now upvoting this.)
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!
