I agree that it would be great to have a feature that filters out everythingthat's annoying here.

I just can't think of anything that would know in advance what I might find annoying. I could pay a personal secretary to do this for me, but I wouldn't trust any machine making this decision.

Also, "annoying" threads sometimes get interesting on page 37 or so... you never know. I recall some situations when I used to ignore a thread and then became curious again when I found out it got unusually active. Sometimes the reason was a specific piece of information dropped in this very thread that I wouldn't want to have missed.
