Earlier quoted context omitted.
There was a problem with multipools exploiting the 'random' block reward - which wasn't truly random - and getting more coins than they normally would. As of now this has been fixed and the price should go up a bit. Also, in about month time the block reward will halve.
Why would fixing that issue cause the price to go up? There was still the same amount of coins created. Also - they apparently fixed it by making the block reward fixed. http://www.cryptocoinsnews.com/2014/03/13/dogecoin-forks-aga...
Multipool miners will generally sell for BTC/fiat immediately, creating lots of supply and thus a consistent downward pressure on prices.
General miners will be more likely to hold or use instead, creating less sell pressure.
By making Doge less profitable to the multipools, they are less likely to mine it, and even if they continue they will get less Doge per block. And that means less supply in the exchanges, which will help the price.
