'i' vs 'I'

The little 'i'

Why do we use 'I' to signify ourselves? Are we that important above all others that we we you a capital I and not a lower case i? Myself, i try to use a lower case to signify that 'i' am like 'him' or 'you', not 'You' or 'Her'. Where does this oddity come from? After a bit of research, i found a sisters-and -brothers-in-thought!:

"There's also the political. I was always bothered by the fact that the first person singular pronoun is capitalized in english - i always thought it was quite self-righteous. Or, as Douglas Adams noted, "Capital letters were always the best way of dealing with things you didn't have a good answer to." Ever since i was a kid, i was told that the world does not revolve around me, yet our written culture is telling me something entirely different. Why not capitalize 'we' or 'they'?"

"So, i started researching where the capitalization of said pronoun came from and was quite stunned to find that it was always capitalized because it always appeared as the first word in a sentence, never stuck in the middle. And then, when it started appearing in the middle, it started getting capitalized out of convention and because people worried that it would get lost in script. Of course, "It's odd, and a little unsettling, to reflect upon the fact that English is the only major language in which "I" is capitalized; in many other languages "You" is capitalized and the "i" is lower case" (journalist Sydney J. Harris).", http://www.danah.org/name.html

So it seems Douglas Adams, and Sydney Harris and this girl thought about the same quirk.
