Howstuffworks is one of the sites that I love to read, but their RSS feed was too bloated, means, I get no choice but to get updates on everything. But that will change now. They have redesigned thier RSS feeds so that I can be more selective in my subscriptions.
Due to popular demand, HowStuffWorks now has 13 RSS feeds to choose from. Pick from Future Cars, Science, Health, Entertainment and everything in-between.
