When Dogecoin was first announced I knew right away that I was not interested at all in it. And I still don't like its stile, the fact it's not being developed any more and so on.
But I have to admit that Doge has found its important niche in the cryptoworld. Without it many small coins would be dead by now. Being Doge one of the base currencies for many exchanges it's possible to trade small coins in the range of prices that are not possible for BTC.
