Sometimes I wonder the sheer amount of knowledge that can be found on the internet is creating a culture where some sort of shallow learning is encouraged over anything else.
I am definitely guilty of this too but I see more people reading blogs explaining some sort of trivial or only theoretically important stuff about, say, web development than people who are working on creating web applications.
It really is another form of procrastination, if not a more dangerous one in my opinion, than randomly starting to play a video game. The fact that you can fool yourself, for the most part, into thinking that you have done something really valuable with your time is really dangerous.
