I'd like to reply, but I'm not sure how to read this comment.

There were always user-unfriendly sites. It used to be possible to easily block the nasty content (Flash), now it's rather hard. It used to be possible to extract the interesting content (Flash) and save it without the junk website. Now it's not. Separation was an advantage.

I agree that the Web is narrowing itself down. One of the symptoms is not having interactive content clearly delineated from the rest.

You seem to come from the same premises but arrive at the opposite conclusion, and I don't understand your reasoning.
