just for the record, the debate between the spelling of "capitalization" vs. "capitalisation" (and its correctness) will not be tolerated in this thread. for all my posts, "capitalize" may also be read as "capitalise". please don't argue with me about it or i'll be forced to modwhore. and that makes me cry.

how often do you capitalize words when typing conversationally (as we do on forums or in instant messages or emails or stuff like that)? do you ever use all caps to shout? do you capitalize just the word "I" (as i used to and still sometimes revert to)? any comments on capital letters are appreciated, really. discuss.
