Couple of things:

First, I want to squash the "Satoshi mined a bunch of bitcoins on his own before releasing the bitcoin chain" idea.  He publicly announced bitcoin version 0.1 six days after he generated the genesis block: January 9, 2009:

According to the block chain history, he generated about 10 blocks total before the announcement.  And we know that he didn't pre-generate blocks because the genesis block contains a quote from the January 3rd Financial Times newspaper.

Second, I have no problem with alternative block chains, I just don't personally like how this particular alternative block chain is being promoted and developed and introduced. In particular, I think it is unfair to keep hundreds of thousands of whatever-coins for yourself, and it is unwise to think that a bitcoin variation that is "almost exactly like bitcoin, only different because... well, just because" will ever have anything more than speculative value.
