Nice try but if you were that sub, you'd also write the i lowercase in the beginning of the sentence.

I once stumbled on a site of a woman who's a sub to the core and was writing otherwise perfectly exept using the lowercase i. At first I considered it odd but then I started feeling she's really brave expressing herself like that, especially when many people might mistake thinking she's stupid or uneducated, (even though after reading a bit of her writing you'd notice the pattern).
Oh, just remembered. A while back, Poppy Alcho in Brunoi explained to some newspawn OOC that it would be preferred that he used correct language. I found that really touching since as a newbie, Poppy's player had been using the terrible "u 2" language and I had told her rather bluntly OOC that she really shouldn't. Many people might consider that a personal attack and quit playing, but she took it well and has been writing properly ever since. Tipping my hat to the player, who ever you are.
