When RefDesk.com says “the single best source for facts,” you can believe it. This may well be the ultimate homepage for a writer. Everything here is literally at your fingertips–maps, news, history–even gas prices! You’ll find a “word of the day” feature (great for writers–today’s is surfactant–A chemical agent capable of reducing the surface tension of a liquid in which it is dissolved) and oh so much more. You have to see this one to believe it. I could go on and on, but why don’t you take a peek for yourself and see what I mean. It’s pretty cool.
