I think because I'm a programmer I rely less on spellcheck than non-programmers, because what I write is full of words mashed together as one (spellcheck if flagged by Firefox's spell checker (and BTW the "if" in "spellcheck if" wasn't flagged by anything)), and words that just aren't words (ngninx). I don't usually add those words to the dictionary, because I'm afraid of writing to a non-programmer and having something pass through that shouldn't.

I treat spellcheck as a real-time shoulder sirfer (surfer), and I generally hit Reply/Send/Make-it-so even though my messages are full of wavy red lines.
