Not cool, man - you just effectively cut off those who took the time to upgrade due to the carefully and considerately planned announcement, in favor of those who happened to catch the thread just when you posted. :\
I hear you. It was a difficult call. It looked to me that the blockchain had effectively halted and I was concerned that we'd never reach block 750. I had to act quickly in the interests of the coin. I think we're in a much better place now than if we had waited.
For what it's worth, I think you made the right call. A lot of people were complaining about the excessive jumps in difficulty, and I believe many of us would simply stop mining because of that.
It would probably take more than 24 hours to get to block 750; with more and more people simply giving up on mining before reaching this block.
