Yes, many people over-develop their sites. That doesn't mean a fast, small site is impossible. But most people are not trying to build the fastest most elegant site in the world - they are trying to solve a problem, and < 100ms isn't likely to be a requirement for most real-world solutions. Likewise, what does it matter how many DOM nodes there are, if it gets the job done?

If you are trying to argue that people should think about whether or not they need a framework, I'd agree. I'd also agree that framework-supported sites do make it difficult to use resources efficiently on mobile devices.

But this post feels analogous to criticizing a parent because their minivan isn't as cool as your convertible roadster. It isn't supposed to be. It just is supposed to get a job done.
