When it comes to software and web design I am strictly an end user.
But, I know enough to know that it’s not that difficult to add or subtract features.
Over the years websites have become substantially better without a doubt. Until, the last few years when there seemed this need to put multimedia everywhere.
Fundamentally, the Internet is/was a “Pull Information” platform. Sadly, it is becoming more and more a “Push Information” platform.
I've noticed of late the ill effect of social media on news sites. They all now seem compelled to clutter their pages with social media interface widgets, often positioned fixed, so they don't scroll off, and you can't get of them. Social media is an internet pestilence!
I have a little bookmarklet I use, which blindly rifles through the current page and disables any elements having fixed positioning or z-index set. Often, that's sufficient.
Another mixed blessing (at best) is the bottomless page. When you scroll to the bottom of the current story, they XHR the next one and stitch it into your view. I suppose this is an improvement on the old standby for boosting impression counts, which was/is the opposite: show you only the first "page" of the story and make you click for the rest. With the new strategy, you just never get to the bottom!
This is in addition to all the advertising malarky, which fattens up pages and makes them load slowly, both as a result of sheer size as well as the need to fetch ad content from slow third-party servers.
