As we bring this namecoin party to a close, I think it important to thank the little people who toiled away tirelessly to kill the last difficulty. And though I will be taking my entire 11.5Gbps back to BTC mining, I look forward to the next namecoin party in two or three months.
That's mean

The party will probably come again one more time, before the 24000th namecoin block arrives. After that, it's unknown due to the merged mining.
Sorry I just had one of my blocks rejected and I got a little emotional.
I think without merge mining, namecoin mining is doomed to these massive mining throughput swings. Unless of course the prices keep up with the difficulty.
