Hacker News
Hacker News is a social news website that caters to programmers and entrepreneurs, delivering content related to computer science and entrepreneurship. It is run by Paul Graham's investment fund and startup incubator, Y-Combinator, and is different from other social news websites in that there is no option to down vote submissions; submissions can either be voted up or not voted on at all, although spam submissions can be flagged. In contrast, comments can be down voted after a user accumulates sufficient "karma" or points gained when submissions or comments are voted up. In general, content that can be submitted is defined as "anything that gratifies one's intellectual curiosity"
