"The Food Lab" and "Taste Test" articles needs their own links under the "Our Sites" tab (or maybe even their own category?).
The articles are comprehensive, self-contained, and have a particular tone to them that separates them from the purely informational and exposition articles that pop up throughout the day. They bring a bit of objectivity to the SE project and should be recognized as such.
That isn't to say that they can't be included under AHT, Slice, Drinks, or Sweets if they deal with that topic. It's easy enough to just tag those articles with the right metadata. It'd just be nice to be able to look back on those SE 101 lessons and peer-reviewed suggestions without having to manually filter through the glops that the crazy search engine returns with.
