IMHO, many commercial model railway web sites are pretty toilet when compared to most other commercial sites. It might be the old "I'm an engineer, I can write my own web site" ploy but sadly these people can't always be the best judge of their own work.
I won't name too many names but even the Peco and Lenz sites look like a sixth-form attempt.
Is this one of the reasons why people outside of the hobby don't think that model railways are 'cool' because the sites they go and find aren't?
I would be happy to point out some of the classic mistakes made including images that are too low-resolution, colours that don't mix, massive long lists of stuff, poor navigation and too many framesets but alas, I guess it might fall on deaf ears.....
