I think that you might be confusing the attitude with the usual crowd. I personally apply the "guesswork" attitude whenever learning anything programming related - snipe a few packages which look right from the Ubuntu repositories, play around in the REPL, write a few toy programs. Then maybe after a few days, go read a few tutorials online and sometime later browse through the manual, but that is only later, after the initial 'guesswork'. Either you're talking about something different, or I don't understand what's wrong with such an approach... Although maybe 'experimental' is a better title? ...correction: On rereading your post a few more times, I realize it's just a misconception of terminology.
