I don't use three letter abreviations for my posts or anything else for which I use full sentences. It really does take me longer to think "oh my god," decide to abreviate it, and then type "OMG." And I see no point in getting into the habbit. If I felt like it, yeah sure it would eventually take less time and save me less than a whole second typing it that way. But right now, for me, it takes longet to type in "OMG" thatn it does to just put down "oh my god." So don't jump on my statements and lebel them as lies.
