Personally I prefer those to be the very end thing and would like ultimate ability to filter. Like we have three types of posts (I think) and I would like to be able to say I want to see or not see each type. I love being able to block urls for news sites I don't find have good articles for links. Basically looking at the post blank I would like to be able to filter based on everything that is there. Algorithms to me are a last line and I would prefer to have things like vote or comment thresholds and such.
