Shares reward generates strong sell side without any generation of a buy side for Devcoin.
That is the problem of a Devcoin - constant sell side generation forces Devcoin receivers to sell them as fast as possible because any new block will generate more and more coins going on sale. All the time. So keeping any coins will reduce its value without any chance to increase.

The reward distribution should be designed to provide the reason to keep the coins for some time (or for a long time). It meas that the Deflation strategy should be implemented. Bitcoin have reduction of coins generated. Devcoin should have the same to succeed. Say reduction of generation rate by 0.1% each 144 blocks (once a day) - it will give roughly 30% reduction annually. 50000 coins per block will become 35000 coins per block in one year. From 36K to 24K - for the next year etc.
Just for example.
ATM the sell side generation is about 220M a month. To keep the DVC price at 1 satoshi there shoud be a 2.2 BTC buy side support each month. It can not just come out of thin air.
So any reward receiver forced to sell its share immediatelly once any buy side appears. Even at 1 satoshi per DVC. Coinsource right now have buy support for only 64K DVC at 1 satoshi.
Any generation reduction will give (small) possibility that coin will increase in nearest distant future. And possible reduce the sell side generation a bit. Possible for significant amount.
So Deflation strategy should be discussed, not Inflation one.
