I don't really see a reason to close a post, ever. If people are willing to comment on it, it's good to go. Threads can go from awesome to bleh and back to awesome. This never happens here. Once threads go bleh they get closed immediately, so we never see that second burst of wind in a thread which can create some awesome experiences.

What is the point, financially? Does Fuzz lose money from having a post closed? No. In fact, I think he might make money from leaving it open. More traffic = more money. And space isn't like having a garage. It doesn't fill up, it's based on servers. Are twenty extra posts in one thread going to make someone go bankrupt? No. What it is going to do, though, is generate more traffic, which means more people viewing ads, and more clicking on them, and more cents per whatever.

This might be related, but I never ignore or block anyone on AIM or MSN or online games I play. Why? Because it makes me laugh to see what kind of stuff they have to say. If they start spamming stuff, and it's all the same gibberish and we get no where, that's different.
