How to estimate (best case) early user growth?
tom: Have you launched something yet?  Paid service?  Free?  Freemium?  Without launching and looking at real, initial numbers just assume you'll be like 99% of the startups out there and get none.  That's what your potential jnvestors will do until they see some real numbers.Seriously, get something real, prove you're on to something, and THEN talk numbers with investors.  You've got a bigtime uphill battle without at least one solid proof point.  Get that, and then hockeystick that sucker up!
