When I write, I use Wikipedia a lot-- careful of course to make sure the info is not too specific. I wouldn't use it for a sole source on archeology for instance- but it does come in handy- especially if you want to find real source material- the source notes on the bottom of the page are very useful as a start. I also use Yahoo! reference - the thesaurus is helpful. But for a more complete dictionary/thesaurus I am finding http://www.onelook.com/ to be far more comprehensive. (I found the link via 'The Phrontistry'-- a fun site on the history of words.) For instance, today I looked up 'wacky.' Onelook pulled up several sites, including the Slang dictionary. When I clicked there, I found not only the definition for wacky (adj. Crazy, zany) but a whole series of interesting words and their definitions, including 'wank' in all it's various forms:
