For most people litecoin was something to do with their GPUs when Bitcoin mining went to ASICs. Coins that use them are scavengers. Litecoin is the coyote, Doge is the vulture, the rest are vermin, insects, and bacteria.
At this point ASIC miners have dominated scrypt. You can't mine litecoin or Dogecoin with a GPU miner anymore the same way you can't mine bitcoin with them.
