I just read an article called Why I don't care very much about tablets anymore, and while I don't have a tablet, and think the author's overall point is weak (not being very excited about tablets, yet still planning to always have one), this part resonated with me:
"Some of the really savvy new media efforts like Flipboard are exciting, but after the initial "wow" factor wears off, these apps mainly serve to remind me that there's already too much good stuff to read out there, and that my life is slipping away from me in an infinite stream of interesting bits about smart animals, dumb criminals, outrageous celebs, shiny objects, funny memes, scientific discoveries, economic developments, etc. I invariably end up closing the app in a fit of guilt, and picking up one of the truly fantastic dead tree or Kindle books that I'm working my way through at the moment, so that I can actually exercise my brain (as opposed to simply wearing it out)."
The same thing applies to web reading for me. I find the web extremely valuable for news, conversation, blogging, and longer articles, but there's still a place for more in-depth treatment of topics in books, and for getting out and living and not always experiencing by proxy. Things that are useful and good may still not always be the most important.
