I think Hacker News has perfectly fine UI but horrible UX. Sorry if i got those definitions wrong. I think the colour scheme etc is perfectly fine but the actual functionality of this site is horrendous.

- There is no search function anywhere

- Go back far enough in the news listings and it just stops. No explanation. https://news.ycombinator.com/news?p=15

- To find the formatting guide for posting comments you have to go through the FAQs?!

- Update a comment and you get redirected to the same form with no message.

I really don't get why a site who's target audiance is web developers and hackers has such terrible functionality on their site. Is it because we are really meant to be reading our news through a REST interface?
