The DOGE phenomenon is pretty interesting. Aside from lightening things up a bit, it does point to the ridiculousness of fiat currencies in general. Essentially we're fighting and clawing over numbers, abstractions if you will.
At the least dogecoin brings a bit of levity to the idea of currency. Currency is simply information and in the void of a better solution, a necessary instrument.
If dogecoin is some sort of absurdist art project, it certainly seems to be working.
It will date pretty fast, just like every internet meme before it. Imagine an AllYourBaseCoin, or a StuffOnMyCatCoin. Or even a KonyCoin. It will run it's course and people will forget it - I'll be coloured surprised if doge[coin] is anything but a footnote in a year.
