oops, hit a key by accident. I'll just continue.

...10-20 hours a day for 5 years studying my subject. It's not mastered easily. It was necessary and it was worth it.

I am happy to try and discuss scientific issues with the "general public." I quite enjoy it, after all, I am a teacher first. I work at a public university so I am literally on call to the people of my state and my country. I am but a phone call away, and that is true for every scientist working at a US public university. I believe it is the same in Canada. I get calls all the time and I spend the time to answer questions. Again, I am sorry I am not called and asked more questions. (Let's admit it, I am a very sorry guy.) So let me ask you? Did you call an expert? Did you invest the time to understand what you can know and not know? Or was it easier to go to Wikipedia and claim knowledge and understanding?

Communication is two way. IMO, I don't think most of the public wants to hear from scientists nearly as much as we read about on blogs.
