What bugs me isn't that language changes over time, but that it changes even though the "change" was an incorrect spelling or usage. Two wrongs don't make a right, but in language, many wrongs make a right. If people use a slang word or a combination of words that are grammatically incorrect, sometimes it becomes accepted, and then is deemed correct. I use shortened terms and some abbreviations, but I go cross-eyed at text like the example Anika gave. I've seen lots of writing on the Internet--conversations, literature, articles/blog posts, etc.--and it saddens me how poor some people's spelling and grammar are. I'm NOT perfect when it comes to grammar; I need to bone up a bit (I have the English 101 textbook, A WRITER'S MANUAL, and it has all kinds of goodies--rules, grammar, usage, MLA standards, and more--that will help me get all smart-like again!), but it still shocks me when I see teens (whose knowledge should be fresh, since they're in the education-filled time of their lives) and adults (who should have learned a long time ago) who don't write reasonably well. I fight the urge to correct others' mistakes (sometimes I do bring it up), but it niggles at me. I know I'm not perfect, and I try not to expect it of others.
