>those people often seem to be there for no reason other than to tell people to RTFM, play topic nazi to such an extreme level that apparently nothing is actually on topic, or just generally berate people for having the gall to say something in the channel. Ops are extremely touchy and seem willing to immediately kick people rather than have actual discussions about things that challenge any of their beliefs about a particular topic or how the channel is being run (any such challenge, no matter how genially presented, is perceived as combative and results in a swift kick).
Funny, it's been my experience that IRC culture was always like this, especially in the late 90s when I started using it.
