Agree that everyone's sense of time is changing. I struggle with this - I can't keep myself from speed-reading/skimming longer form text.

I do think this is problematic, and not all good. A great deal of knowledge still requires significant length of text to convey -- sure, the retrieval cost for any individual limited concept on the internet is much lower, but you're not going to develop a rich understanding of, as a hyperbolic example, the history of China, from one article or from Wikipedia.
