Thanks for the link. One very notable part of the Facebook dilution is that Eduardo signed on to a shareholder agreement authorizing it, at least in part. We unfortunately don't have the agreement in question to see how it worked, though it seems that, by way of the agreement, Eduardo was not invested in the new entity as fully as he should have been. The interesting question is if he ended up with roughly the same share he would have if Facebook had simply taken on the new investors and not tried any "dirty tricks." IANYL, but I'd say this: if you're at the point where you have more than a basic agreement with co-founders, you want a thorough, diligent lawyer working with you on these issues.
