Launchday seems to be such a great product. I just have one fear about the sites created using it having almost the same look and feel. I like how Tobias van Schneider’s Semplice overcomes this, each of their sites look so different.
One way of doing this is to provide the users to add their own custom blocks. May be you can make this like a community thing, where users could also contribute to create blocks.
Dave, wishing you all the luck for the product launch of Launchday :)
