In my time on slashdot.org, i went from a troll who got IP banned to having about 15 or so articles accepted for publication, generating hundreds of interesting comments.
Now the guy who created that slashdot thing is gone. Why did he leave? The internet had changed, and he didn't think he could 'objectively' decide how slashdot should change with it.
What, specifically, caused him to feel that way? We may never know.
