Basic story is that if you or your group controls a large enough collection
of the bitcoining hardware, you can benefit by NOT publishing found blocks
early. That is a very interesting "hole" but one that would be quite
difficult to exploit, in that you would have to have control of a VERY
significant set of computation. They also have a pretty easy fix, which
should be straightforward to implement.

I don't see this exploit as being damaging to the long term perception of
Bitcoins.

It is interesting that the natural curve has caught up to the last
bubble... though the curve does look just a little steepish at the moment.
