I am one of those classed as a ‘silver surfer’ in the UK. My fist computer was 11 years ago after I had retired from paid employment. Wendell and H-J are right on the money, I am sure, with their observations.
Search engines and pc programme guesses can be quite interesting.
Try just typing models and see what you get: I bet it won;t have much connection to railroads.
I am on Facebook purely for a couple of railroading friends and one or two dealers and museums. As I did not give my location it kept asking where I went to school/college. All guesses were in the United States!
A search for a local company never gives me a location closer than 25 miles.
I am content with that and over the years have soon learned to sort the chaff from the wheat.
The great thing about the web is that it gives information when researching something. Some info can be suspect - historical or political slant for instance - but then so are newspapers. It is surprising how many people implicitly believe the newspapers. WOW! where have they been hiding.
