The tags are there for a reason. The categories make for easy searching of what you're interested in. Many people browse this site for only a few categories. Like I use "eat what you want" to get my daily dose of tantalizing food, but lately the entire category is filled with nothing but bullshit with a food post sprinkled in. You're not clever tagging your porn or whatever gross video you submit "eat what you want". Or tagging posts with everything just to maybe get more upvotes. Just stop.
