I used to read quite a lot of books, library books and personal books. Mostly fiction and popular science, I hesitate to admit (not hesitate to read them, just hesitate to admit because they are 'lesser' books). There are a lot of things that I couldn't tell you whether I have read or not, let alone what the main points were. Now I mostly read online and read pages every day that are forgotten within hours.
Every day or two I find somethings really interesting and hold onto those ideas for a while, but they fade. How many great ideas did I read from Kathy Sierra? Lots... I think. As long as you don't ask what they were.
Am I really doing this just to feel good about saying "I've read that!"? Am I reading for the occasional "ooh, I read something interesting about that once... where was it?" feeling of contribution?
Am I missing something fundamental about reading and remembering that other people get - ought I to be studying books instead of skimming them? Ought I to remember more of the content?
Am I really a better person for having read more books? For having been exposed to certain ideas?
