It is bad enough when a company misspells a word on an advertisement or use the wrong "there," "they're," or "their." Why do national chains have to take that extra step and purposefully use the wrong spelling of a word? For example, Chick-Fil-A is famous for billboards featuring the trademark cows painting misspelled words. When and why did this become a good advertisement? I can imagine that years ago, if a company attempted an advertising campaign like this, the signs would be laughed at and nobody would take them seriously enough to purchase from that company. Now, it is perfectly acceptable to let these companies plaster misspelled words all over the place where even children learning to read can see them.
I may not always use impeccable grammar but if I were going to create an advertisement that would be viewed nationwide, I would consult an editor or someone of the like in order to proofread anything I may have written.
It seems to me that these billboards are just another sign of the times and of us "dumbing down" our children.
It goes hand in hand with the language kids (and sadly enough, even some adults) use in text messaging or comments on Facebook. I don't consider myself a grammar expert but I certainly don't see it as a waste of time to capitalize "I" or to write out the full word "and" instead of "n." Is an extra five seconds really too much time for you(general) to use when you're typing something?
I think it's time that it becomes the *cool* thing for kids to use correct grammar and punctuation. It just becomes so much more enjoyable to have an electronic conversation when you don't have to spend 10 minutes deciphering what it is the other person is saying. I spend time debating online with other members of a "hot topic" debate board and if I come across a post with awful "text speak" or something, I cannot even take them seriously which leads me to just skip over the entire thread.
I cannot even imagine what the technology will be like in 10+ years when my kids become teenagers but I can assure you that if they are texting or IMing or chatting on the computer, I will hounding them to use correct English whenever possible.
