warm, fuzzy and eccentric

Dunno if I'd go along with warm and fuzzy (well, maybe fuzzy, given an appropriate defintion of fuzzy) but I certainly find it a usable tool. It will find typoes and misspellings. You just can't count on it to give you reasonable alternate choices, but there are other tools that will do that better than many spellcheckers I have seen. It also provides sempiternal* hours of mindless amusement (simple pleasures for simple minds).
