"You're a prick" is not a threat. If we can limit it to proportional consequences, I'd agree with you. Do you think calling someone a prick merits a ban from a country? (let alone a country that holds freedom of speech as a fundamental principle).
The problem with fast food is not the food, it's the way people use it. Once in a while - no problem. Every day - big problems.
The problem with RSS is not RSS, it's the way people use it. Add a few sites whose content is enough interest to you that you read everything they publish - RSS is awesome. Add every site you come across that might produce something you're interested in between stuff you don't care about - big problem. You've invented yourself a new daily chore, and, worse still, you think you've done yourself a favour by doing it.
Same with twitter, too. Follow crap-spouters and you'll think that twitter is nothing more than the what-I-had-for-lunch stereotype. Follow people who 'get it', and you'll be annoyed at that stereotype.
