Yep, the Internet is particularly great for people with short attention spans, who apparently can only read and write a few sentences at a time, without any depth or focus.
I've written for a bunch of magazines AND websites, and one interesting aspect of the net/print question is that even though the Internet can publish much longer, in-depth articles at far less expense than printing them on paper, Internet articles are usually shorter and provide less actual information. The exception is when they're "reprints" of paper-published articles, but many of those are edited to much shorter length for the short attention span of Internet (and "smart" phone) users.
