Mobile devices have overtaken the internet. Predictive spelling, used as it is by most people, sucks ass. Pardon my frustration.
People are more concerned with getting their thoughts online than they are with being understood. Excuses like "language evolves, deal with it" or "stupid spell check" are just another way of saying "I don't care what you think. Look at me!" or "I can't spell my way out of a paper freaking bag, but look how smart I am!"
Just take the time to say what you mean without being pretentious (a near impossible task for a lot of Treknoids), and have a good time.
Row, row, row your boat ...
