I discovered HN Special for Chrome a week or two ago, and I'll never go back. It adds every feature I've ever wanted (better, higher-contrast design; foldable comments; user info hovers, etc).

Interesting note: the same guy who wrote the original 2048 game wrote that Chrome Extension! Pretty great stuff.

HNES is the best, I hate using Hacker News on computers where I cant install my own Chrome extensions because of this.

Disclosure: I've contributed to HNES before.
