I have a clue! I understand what Galt's Gulch is (internet communities appear to be the only hope for a real one) and according to google, Jon Galt is a porn star. But I don't understand why you get on MY case when abbreviations are used all over the place. I learned this abbreviation on FR along with many others. At one time I had a list of internet abbreviations but must have deleted it. I can try to find another if you desire.
I just believe you like to argue and therefore would not be a good candidate for living in "Galt's Gulch" where like minded people would have to get along with one another-IMHO (oops I did it again).
I think you should try to imagine how YOU are perceived.
Are YOU trying to impress someone?
Yes - I'm trying to impress you to use language properly.
No - You had better research the name John Galt. If you have porn on your mind you have definately crawled into the gutter instead of looking up to the origin of the John Galt name. There are two John Galts. Do some research.
PS. I have been using the internet even before 99.9% of those currently on the internet even heard of it.
PPS. I pick on anyone and everyone that uses language improperly. All societies declined when the use of their language became slang and descended into the gutter. I am just trying to prevent further declination of the English language. Look at history of other extinct countries and will see that language, art and morals all declined before the country became totally despotic and then extinct.
