Certainly the original post has useful information for those who want their writing to be taken more seriously. However, the issue here is orthography, not grammar. (My apologies if someone has already pointed this out, as I admit I've only read the first post and the last two!)
ETA: except for anyways. All the other contrasts, I think, exist only in the written language, and therefore are really just spelling or punctuation errors.
