You say that, but Flash was basically a drawing program with a timeline - this makes it much easier to doodle all sorts of things compared to building a site with Javascript and HTML.
However I get the point, but I feel it is important to stress this difference that you bring up.
My 18 year old clueless self seen turtleshell.com randomly, thought it was amazing, looked up flash, did stuff in Flash, 10 years later OOP. 10 years after that, software engineering.
My 18 year old clueless self today would want to be like "somethingcool.com" but I would have to troll through about 12 months of tutorials to see something on the screen.
I'd work in a factory.
