The Lotto is "absurd" but I still play it when it reaches those ridiculously high levels. Spending[1] $400 on CandyCrush is "absurd". The $999 iOS app "I'm rich" was "absurd". The idea such a thing as bitcoin, from an anonymous dev, somehow reaching $1,000 each is "absurd" .....but here we are. :)
As much as I thought Dogecoin was ridiculous, I now know that I better go get some... just in case.

That's not absurd at all. Might be absurd to you if you are absurd though or not good at Math, like lots of other humans apparently are.
Litecoin wasn't a great idea, just a copycoin. It wasn't even innovative on the scrypt part, they just copied Tenebrix and changed the branding. So it's the same crap as Dogecoin.
Namecoin is a great idea, and we definitely need to decentralize the web, but I don't see it taking off soon.
Whether a copycoin's price goes up a lot or not does not tell us anything about whether it was a great idea or not. You seem confused on that part.
