Agreed.

the relentless nagging by some sites to install the mobile apps needs to die.

Just like the other popular post today lamenting the terrible state of scrollbars and other UI elements that has degraded the desktop UX in recent years....

Even the attention to mobile web experience seems to have degraded.

There was huge focus on optimizing the very limited bandwidth and resources on mobiles... there was WAP and XML ...people atleast tried. Now a 2 year old phone that is effectively a supercomputer struggles to load simple list pages and blogs.
