Love your dictionary? Love all the time-tested words, but cringe when you hear someone use the word "impact" as a verb? Willing to stand up for your words even in the face of death-threats? Here's a blogger who knows more about this than most people.
Here's a fun thing I found in my travels tonight: ninjawords. It's a VERY FAST dictionary program. Why should you care about a really fast online dictionary? I don't know, but if you try it, you might understand. It's now among my favorites.
Okay, and if you're truly among the word-obsessed, you might want to try out Wordie, where you can join a community of people who revel in making word lists ("words you love, words you hate, whatever"). I haven't yet felt inspired to add words here, but I've had some fun wandering through and finding really good words. Like "flummox," which has always been a favorite of mine.
