There's a really interesting subtext about web-apps here. So much so that I think it deserves more follow-up.<p>Yes, you are correct: you will not take so much care in the future.<p>People are wonderful pattern recognizers. Show them a system where you vote up and things go up and you vote down and things go down? They grok it. Where you punish people by down-voting them and reward them by up=voting? Makes sense.<p>But start mucking around so sometimes when you vote up the article goes down? Or sometimes you can vote and sometimes you can't? Or you can't vote now, but you can vote in 12 hours? Or you can vote for this guy, but not this other?<p>Eventually they just say "Screw it. It's effectively either random or designed especially to piss me off. Therefore I will not take it seriously"<p>Oddly enough, the more attached people are to the gaming/karma aspects of the site, the more this will annoy them. Also the more annoyed they are, the more likely they are to start gaming the system -- since in their minds the system isn't giving them a "fair shake" to begin with.<p>Lots of interesting insights into human behavior with complex systems here. Of course I'm just speculating, but it's important stuff for anybody running a public site.
