Suggestion to improve HN quality: allow headlines to be editable by high-karma users
This will allow more clarity on the homepage, so that it's easier to see if an article merits a click. For example, the headline "25 Things I Didn't Want to Know About You" (currently on the homepage) would become something like "Time Magazine reporter finds recent facebook meme annoying".
The initial headline could be preserved on the comments page as "Originally titled: ________".
