Like: The interesting tools you find when people "show" their tool, and then everyone mentions a bunch of other similar tools in the comments.

Dislike: Down voting. Down voting just makes for an echo chamber (as someone else already mentioned.) It's a terrible, nasty, way of punishing people who's posts don't fit the popular cliques viewpoints. It should be replaced with either a mandatory "this is why I down voted" comment, or flags that everyone can see. Like "off topic", "insulting", "spam", or things like that. At the least, it should cost karma to down vote. Oh, and if you down vote, or flag, and it gets reversed, you should lose karma.
