Shouldn't all the major pools raise their soft cap to 500kB or 1MB.
Just a thought. I think this would make room for the tremendous growth that we have seen this month.
I wanna see what this puppy can do.

The only major pool that hasn't to my knowledge is ghash.io. BTC Guild, Eligius, and BitMinter are already on 500K or higher max size blocks.
EDIT: Slush is definitely still on 250K on at least some of his nodes, if not all.
