I agree with DHH that Rails shouldn't be dumbed down (see his Railsconf 2012 talk https://37signals.com/svn/posts/3171-keynote-by-david-from-r...). Cooking with Rails is like cooking with a real oven, not an easy bake where the end product tastes terrible. Somehow new people need to know that Rails is a real framework that can burn you if you're not careful.
I can't think of anyone though that promotes that method of building websites anymore though, even PHP proponents advocate some flavor of web framework. It just happens to be an easy entry point for using PHP, and once a new developer has built some project momentum for the first time, they're reluctant to start over with something new.
language being more popular than a framework! sure :)
bring one framework that is more popular then rails?
google trends proof: http://www.google.nl/trends/explore#q=ruby%20rails,%20symfon... (many people make searches w/o the 'ruby' search term, so rails wins by a larger margin)
some proof here that php is a lot more popular then ruby:

and java more popular then php... and WOW FLASH!
http://www.google.nl/trends/explore#q=php%20tutorial,%20php%...
we a should all use flash, it is the most popular, more so the java!
gosh.. im trying to prove you're comparing apples with bananas and now i find out i should be coding in Adobe Flash (tm).
</joke>
anyway.. i believe php is only marginally more popular then rails, for stuff that involves "web app development". that's what rails made is for. php is used a lot for ftp-ing scripts to cheap webhosting, something is done a lot less with rails.
But if you care about Rails uptake, aren't those bad things?
People don't like being confused. People don't like feeling stupid. If their initial impression of a system is "this is confusing" or "this makes me feel stupid," many if not most will simply go look for an alternative that isn't confusing and doesn't make them feel stupid, even if that alternative is inferior in other ways that aren't immediately apparent to the newbie.
