Something like https://bitcointalk.org/?topic=1154536' is better.
Well, the worst you can say about BIP 101 and it's two-yearly doubling from 8MB is that it only might work. I still think that's not good enough!
Said it before, I will say it again: dynamic resizing. This should shut everyone up, because if 8 MB, 20 MB or even the 8 gigabyte limit where BIP 101 tops out, if any of those are the "right" blocksize, then it will happen irrespective of what your opinion is. Unfortunately saying "should" isn't necessarily good enough either, but I think it can be done.
