Mostly I'm an editor, my knowledge is drawn from a variety of sources, and I find wikipedia to be very useful, but it often suffers from being both incomplete and written in a blocky style without revision, and even simply being drawn wholes[c]ale from external sources. I'm looking forward to the Wolfram Alpha engine being tied to wiki and google. Duckduckgo is a brand that already uses it, and I use it when I don't use google. With the wolfram engine, the scale of wiki can be improved drastically.
