The crux of this is that there is increasingly a fundamental difference between "websites" and "web apps".
If your site is essentially a collection of documents, then I expect it to work with standard browser navigational tools, be easily linkable and function without Javascript being enabled, it should also work in old browsers.
If you are doing an application on the other hand, It's far more reasonable to expect an upto date browser and JS etc. I almost don't want to know that it is running in my browser, because the navigational toolbar in my browser is probably a bad fit for whatever it is that your application does.
Of course there are blurry bits and grey areas here. But as a rule, the front end of your blog is a website and the "admin panel" is a web application.
