I once applied for employment at a rather dodgy firm. Cancelled the interview though when I looked online and saw what people had to say about it.
why do you always press the tab button when you make a post
To answer your question, I do it as a matter of tradition at this point.
And I think
that is the most Bushie-esque thing you've ever done.
Also, I recall reading about why the whole extra space thing was necessary in the really old days of the internet; something about every character took up the same amount of space and in order to tell easily where a sentence ended, people would put two spaces after the period (though I guess that doesn't explain/apply to the tab thing).
