I guess superblocks are good for early starting miners, but I don't see the advantage to be honest. If you're there early then you'll be able to get the blocks quickly enough anyway because fewer people will be around. It's really the same problem with the difficulty except a different way of doing it.
better way, would be to start the superblocks further into the block chain, say around 10,000 blocks or so, otherwise, your just giving bot nets and huge, lownlatency miners, millions of easy coins. Diff will be higher, and, they will spread out more evenly. A pool may even be setup quicker. See, the main goal, for a coin starting out, is to have a lot of people, will a nice bit of your coin in their wallet, rather than a select few, holding a majority of the coins. The more people who have your coin, the more people who are invested in it, and want to be able to trade it. The mob rules, as they say
