I think it definitely is. I think that with email and text messaging that auto corrects your words or basically spells them for you, it's not doing anyone any good. Though, you could make the case that it's the way of the future and you won't really need to know how to spell, just as long as you can read. Either way, that's scary.
Also, all the abbreviations that people use like lmao, brb, wtf, and crap is getting outta hand.
