Anil Dash wrote a list of ten internet rules, which all make pretty good sense. Here's one that is pretty well known to bloggers. Or should be.
If your website's full of assholes, it's your fault.
That's the rationale behind Neatorama's comment system. We have few rules, but if a commenter breaks them, they are edited/warned/deleted/banned depending on the behavior. That's to make it nice for everyone else, because we LOVE it when people comment to add information, make jokes, tell personal stories, or just give feedback on a post.
People will move mountains to earn a gold star by their name on the Internet.
Well, we don't have gold stars, but we do have ♥s for comments (which anyone can hand out) and the "comment of the week" (which doesn't happen every week, sorry). Besides, if you are a registered Neatoramanaut who has not been edited, chastised, moderated, or banned, you are part of an elite group of wonderful people, so pat yourself on the back. Here's a rule that made me smile:
Given enough time, any object which can generate musical notes will be used to play the Super Mario Brothers theme on YouTube.
