Rob was concerned PoG v1 had some holes specifically with the ability to game the donation scheme so you can get the biggest percent of payments by running hundreds of BiblePay QT wallets.  PoG v2 has some of those issues addressed by utilizing concepts from an altcoin called Lynx (getlynx.io) via their HPoW (Hybrid Proof of Work) which uses some clever tricks to equitably distribute mining rewards using code and data from the blockchain.

I'm in support of PoG v2 with the caveat that it replace Proof of Work (BiblePay calls it Proof of Bible Hash PoBH) as a test. I think PoG v2 can be viable, but just need to test the waters slowly. It can also replace PoDC, but needs more support before we think about removing PoDC.
