I thought I'd start this in answer to a comment Judy made about one of my answers. The comment was in this thread:

I wrote that I suspected the OP was from the UK and Judy marveled at how I knew that. Tickle supplied the answer. It was the OP's use of the term "estate agents" rather than real estate agent or broker as most people from the US would write.
But that got me thinking about other ways we can deduce where a person is posting from based on their use of language. One prime example is the use of the pound symbol rather than dollar sign when entering currency amounts. Another is using colour rather than color or similar spelled words. A recent example was one OP's use of the phrase "council house", which I believe refers to some form of public housing.
There are other clues for other locales so if anyone wants to contribute their favorites feel free.
