Ah, that's a pet peeve of mine... I've always loved looking at the guts of any library I use, first because I often learn something new, second, because otherwise how can I rely on it?

But, a lot of programmers I know, don't look at the code for some reason, they just search and search on google, then go to irc to ask around and waste a lot of time when they could have found their answer in 5 minutes...
