Pinky and the Brain? Heck, this is beyond nerdy. I don't even know how to qualify it, but it always makes you snap back to the fact that you are not reading a normal run-of-the-mill encyclopaedia. (And it makes me wonder, who even takes the time to write this kind of incongruous cross-referencing?)
What's the point of reading about a bridge in the middle of nowhere. Absolutely nothing. Except it's a great story.
Which is why derivative stories are also interesting.
Was the Pinky and The Brain story boring. Yes.
Was the Falling Down story interesting. Yes. It was about a hidden Easter egg referencing the bridge and the location it’s in.
As someone else points out who cares about lists of Olympians from 30 years ago, no one. Some random name ran around a track. Who cares about fictional ducks. Most people. Donald Duck alone must get a lot of the population, he has had a real (good/bad) but remembered impact to most people’s lives.
You're taking about a quality issue. Not a nerdy issue.
Bit more useful organization:
So I can understand thinking it didn't exist! It actually took me a good 10 minutes or so to find it on Google (and most searches take < 30 seconds!)
