The dev Rob, does not really post much on bitcointalk, you should probably head over to cryptocointalk!
Who is the dev?
My opinion is that the problem starts when there's PoR and scrypt PoW running in the same time. I think that a better idea would be to have pure PoR or PoS/PoR, because it's safer. Maybe instead of repairing blockchain every day (or twice a day), it would be better to finish PoW and switch to pure PoR (or rather PoR/PoS) now? And I wonder if the PoR block minting is a good idea (let's compare it to curecoin, where the research makes no blocks but a normal trasfer hashed by asics, here it should be hashed by PoS). By this ocasion the reward algorithm could be improved: no halvings, but more proportional amount of coins to the amount of points in long term.
We spent almost 4 months discussing, voting as a community, and testing the Proof-of-Research wallet. Most of the information about testing and discussion is contained in these threads:

https://cryptocointalk.com/topic/1331-new-coin-launch-announcement-grc-gridcoin/In all there are well over 150 pages of in depth discussion that lead to the current launch of Proof-of-Research.
The new wallet is pure Proof-of-Research plus Stake now. Only the wallet in retirement uses scrypt Proof-of-Work and the community decided that 6 months was a sufficient amount of time to convert the Classic coins to the new Research coins. For the next 6 months there will be 2 wallets, the Classic wallet that runs on Proof-of-Work with a reduced reward and the Research wallet that runs on Proof-of-Research plus Stake.
