Mmmk. I do believe I am starting to veer away from my original decision about net speak. For one thing, I like how this is called "cracking down on grammar," yet some of our own moderators don't even use correct punctuation and capitalization. I have just a hard of a time trying to decipher posts made by those who fail to type grammatically correct than those who use common shortcuts to shorten a lengthy post.
I agree with what some of the others have said on here, if you don't understand it, don't read it. There are plenty of people on this forum who can understand it, and in today's modern world, "net" speak is a very useful thing to know. I will say, it does seem a little odd that one of the words on the list is "lol" when I know many people who don't understand it, although shortcuts like "u" and "r" are a bit obvious, yes?
And again, this seems to have turned into a grammar thread, when net speak has absolutely nothing to do with capitalizing and using correct sentence structure. You can still capitalize the first letter of every sentence using net speak, and can also have correct sentence structure(minus the fact that you are using quick shortcuts).
