When you sit back and look at it web application development is a total disaster. If you tried to conceive of the "ideal" UI platform (or even a "good" one) you would never, in a million years, come up with what we've got now. It is a testament to the skills of everyone in the industry that things like google maps, Gmail etc. can be built on this sky-scraper of bananas. No wonder it is hard to learn.
