My personal experience is that customizable is a great thing, however, it might turn out to be an echo chamber if over customized. Too many familiar contents, need more surprises.

also need a "hide" button. The most frequently used button in reddit was mark a thread as seen by hide it, don't wanna see it again.

The risk you're talking about re: echo chambers makes sense -- so far, we're trying to mitigate the issue by making it possible to 'follow' both the customized and uncustomized versions of the topic. Any other ideas are always welcome.

'Hide' sounds like a really neat feature!
