I refuse to upgrade just because Gavin says it should be so. Let the actual market decide, in terms of fees and such. I detest centralized decision making - and frankly have some suspicions about Gavin ever since he caved in to meet with the CIA.
I completely agree that we should not make changes just because Gavin says so. I also think that even if Satoshi were to reappear just to say that he was in support of larger blocks (which I believe was his original intention), it should still not be decided by vote of authority. I do believe that gradually raising the block size limit to accommodate a much larger user base on-chain is the approach which will be most beneficial and fair to everyone in the long run.
However, that's just my opinion which is one of many. Allowing the market to decide is really all that CAN be done.
