The killer feature was the no BS UI of the website. The site looked very clean, white background, bluish links and on click or hover had a fresh yellow background. Fonts were small. None of the links were underlined if my memory serves me right.
Unfortunately I had not upvoted and have tried keyword searching through HN but was unable to find it. I am not sure if it was a SHOW HN but have tried searching a compiled list of show HN too but unsuccessful.
If anyone knows what I am talking about, it would be great if you could point me to it.
Edit: links looked like that on craiglist except onhover color
