The author lost me at "their".
How many of those under fifty, including those with undergraduate or even advanced degrees, know the difference between their, there and they’re? I think it is rather low, I have actually seen all three used within one or two sentences here on FR and all three used INCORRECTLY. One response to something I posted on the subject said all three should be spelled the same since they are all pronounced the same! Apart from the fact that one is a contraction with an apostrophe that sounds rather strange to me since I have always pronounced them differently. Having been raised dirt poor on a little farm in South Carolina and actually having walked behind a mule growing up it is rather amazing to see supposedly educated people making errors which would have kept me in the fifth grade until I had a full beard.
