I wholeheartedly agree with +Rachel Houghton although I don't have anywhere near the same credentials. One of the reasons why I like G+ is the fact that you can use whole words rather than twit-speak.
I very rarely use slang, be it within a post or a text. In fact, it's not uncommon for me to write a paragraph before I hit the "send" key. Those to whom I am writing will often fire off 1 or 2 quick lines, but I tend not to function that way. Not only that, there's been some instances where I have had to look up some of these insane abbreviations to know what is being said. I have finally got many of them in my head now but still tend to use longhand.
I try to limit my use of texting abbreviations even when texting, while a g2g, or AFK once in a while is fine, I find myself wanting to strangle people when I see them in E-mails, Blog Posts, or things like G+ Comments.....
I spell and punctuate correctly (even using an old keypad cell phone) and then, if I run out of room I go back and attempt to compromise on which grammatical crimes I'm willing to commit to make it fit.
I've never understood the drive to use abbreviations outside of the old clamshells and candybars, now that we have solid QWERTY boards on the average feature phone, it's just sort of the end of that necessity.. And it's never made a lick of sense on a PC.
I've never liked texting slang, it's just lazy. Considering keyboards like SwiftKey will take care of the oh so laborious task of having to hit a few more keys to spell out a word, I don't see a reason for it.
I never intentionally leave out vowels or use numbers instead of letters unless it is purely used for mockery. I HATE reading texting shorthand everywhere I go. It isn't that I can't read it or figure it out, it just makes the other party look juvenile or stupid.
+lerato majikfaerie , 24. I grew up using email for most of my back-and-forth internet communication, so maybe that's why typing in that shorthanded lingo is a feat that requires actual intention for me at this point..
Normally I write it out. I have a real pet peeve about the use of slang and text slang in place of proper grammar at inappropriate times. I cannot count how many people's applications I threw out because they didn't know how to write let alone speak. Or, they come to an interview (for a customer service position) looking like they could open a can with their face and talk "like dis n dat an u know whut ah mean?". That said, I am guilty of quick comments being text shorthand. I do use text shorthand quite often but the auto-complete usually fixes it. However, if I desire you to take me seriously. I am good with language and use it accordingly. I am hooked on Phonics!
I prefer to use full English sentences with correct spelling, grammar, and punctuation, and only resort to abbreviations in order to get the letter count down below whatever the cutoff is. But I do use "texting language" for the emoticon-type additions, such as LOL, ROFL, etc. Those are just awkward to read as whole sentences.
