Then you would have liked the friend I had in the UK. That was impressive. At first I had to read his posts 3 or 4 times before getting any sense of what the heck he was talking about. And this was highly technical stuff about market inefficiencies and what you have. He used words that most people never heard of, but were exactly the right words to use. And the pace, was astonishing. It later turned out he had worked with top executives in the US, with Intel and a number of other big companies. Advising them on a number of matters. Of course this was no surprise to me. He was a rebel. Always looking after the best interests of the public. It felt proud just being close this guy. Of course he had a lot of enemies on the message board too. People with vested interests.
Both you and RD write very good English. My impression is that posters generally have a very good command of English when it comes to vocabulary but some posters make a few elementary grammatical mistakes.
