forks are bad. People who don't acknowledge them are ignorant of what it means. PersonA sends a transaction on ChainA. ChainA forks and is now ChainA and ChainB. Person sends another transaction on ChainA. If ChainA is resolved as the dominant chain the transaction gets recorded and there are no problems. If ChainA loses dominant and ChainB wins then the transaction is lost. You lose. What sucks is that some people are transacting on ChainA and some are transacting on ChainB. No one knows what the dominant chain will be until they resolve. You are pretty much gambling with your coins if you send them while a fork is occuring.
That's the least of the problems with it. The real issue is, all it would take is a handful of cops showing up at Doge mining servers to take over the chain. Doge network is not distributed enough, and P2pool should be used about 10,000% more than it is now for PoW to work properly. Bitcoin has the exact same issue.
Hybrid PoW/PoS might take over if these problems continue.
