Creating sites is hard. You have to know: programming language, database, server, os and framework.
Creating sites is forbidden. You visit an alternative search engine or an educational site. Soon, it becomes an ad site. Creating sites is for start-ups, not for firefox add-on authors.
That's what you get. People are creating fewer sites.
There's nothing stopping anyone from dumping an HTML page on to a server.
But I'd agree that less people would do that because the alternatives to creating your own are so strong. Why learn HTML at all, when all you need to create a blog is to login to Wordpress.com?
