Starting up a start up

My family has been working on a Homeschooling related startup for a few months now. We are getting semi-close to launch time so we are about to begin telling people about the website publicly. I've been working on the blog and teaser page for the last two days (I'll post the links here very soon).

I recently re-read 37 Signal's Getting Real book (a great read) which inspired me to do a "hollywood" launch (with a teaser site, then a preview site before launch so that when launch comes, you have a database of email addresses to which you can announce the site's launch). So I've been scouring the web for experiences and techniques from people who have actually used this tactic (most "web 2.0" websites). I could barely find anything. Maybe I just need to learn what key words to use, but any how, I'll do my best to blog the my experiences (from developing the pre-launch site to what the reaction is like).
