It sounds easy to do so. Too often however, I find myself reading how-tos and copy-pasting tutorials while building stuff...and forgetting everything after I finished.<p>I have the feeling that google has significantly changed the way I store things in my head (for the better or worse).
Instead of remembering how things are done and why so, I at best save a mental hyperlink to the information or worse, I just rely on google to be available and give me the tutorial/code snippet I need at that very moment (and again forgetting all afterwards).<p>Being forced to reproduce what you've learned at least once without having google is actually useful (at least for the way my brain works).
