We are all saying how much less effort it takes to type AFAIK instead of As Far As I Know, but think about it, now you are wasting more time having to answer these questions, when you could have typed the full sentence and avoided this ...sorry just thought i would go in depth lol (sorry laugh out loud )
I use that all the time, i dont know why you are all complaining tho, i bet everyone of you are guilty of using some sort of abbreviation. Things like POS, TBH, IMO etc, so whats the difference?
