Off topic, but I'm very curious... why did you decide to launch on Labor Day? Aside from the slight symbolic connection to your product, aren't you concerned that you'll have a much smaller audience due to the holiday?
I literally conceived of this idea a month ago. My day job is in finance, so this break is the first contiguous block of time I could find to put it together. As far as audience is concerned, its true that the audience is smaller but that's good insofar as emergent problems can be addressed before people come back on Tuesday :)
