Traditional Proof of Work coins are getting replaced by the sleeker (from an electricity usage point of view) proof of stake and masternode coins. They also include features like smart contracts, invoicing, etc.
We probably need to update Devcoin to modernize it, which is going to mean a complete hard fork. Two coins I'm involved in, DMD Diamond and DNotes, very recently did this. It involved among other things taking a snapshot of the network and then starting on that basis with the new fork, beginning again at block zero, effectively swapping out everyone's old coins for new coins.
masternodes are not a good idea, if you try to HARD FORK devcoin it's no longer DEVCOIN and make proof of stake clone coin please make the algo linear to distribution jmho
You can have a POS coin without masternodes. DNotes is currently doing that. Of course we would want the algo to most closely represent what Devcoin stands for and what it does best. A good coin needs to have good leadership. That's really what makes the coin what it is; the tech helps, but it's pretty neutral.
