I'm with you on this. I always thought it was kind of silly but I guess having even a single page that says "Launching Soon!" is better than nothing at all.

<shamelessPlug>My startup, http://www.loggur.com, says we're launching soon but I actually did take a few weeks to describe it in as much detail as I can on the site. There are at least a dozen pages of details.</shamelessPlug>
