I have no idea myself really.
For instance, I found feeping creaturism thusly:
I went on to wikipeida to look up information on Maxis (I'm thinking of trying to become a game designer at Maxis. That's the goal anyway). Somehow I got sidetracked to the article about StarCraft: Ghost.
That led me to a reference about the long development time. Specifically it mentions a Penny Arcade comic linking it to Duke Nukem Forever.
Duke Nukem Forever led me to look up Ultima 9: Ascension (which I have (and hate)).
Ultima 9, while it doesn't specifically mention feature creep, got me thinking about it (I knew of the term before hand) so I looked it up.
I never know what I'm going to learn when I go looking on wikipedia.
