I agree pretty strongly with TheCharlatan's central points, I've been thinking about this subject for a while. PoR is a nice notion, but I don't think it meshes well with BOINC because BOINC was never built with the kind of security concerns in mind that are needed for a reliable blockchain. Our current fundamental process of rewarding BOINC work on top of a PoS blockchain really strikes the right basic balance between a secure blockchain that is needed for Gridcoin to be a viable cryptocurrency and the kind incentive we want to provide for people to volunteer their computing capacity towards BOINC scientific endeavors. The efforts of developers are better spent trying to do those two processes as well and fairly as possible, rather than attempting to blend them in a way which is all but assured to sacrifice blockchain security.
As a community, when doing outreach/marketing and especially when comparing to other cryptos, we should be careful to be forthright about how the project is actually functioning and is likely to continue to function. Using PoR (even though it sounds nice) as a description of the project at present is muddy at best and possibly outright dishonest.
