Funny, but I've made suggestions in the past.

For those who are curious this is the "suggestions" made

Inclusion of every new post or exclusion of every post from a particular website at user's discretion. Regexp based? Just to prevent the site from effectively becoming an RSS reader.

Also suggested was a killfile, which I think is the better suggestion.
