30% growth every week for 18 months would mean total growth by nearly a factor of a trillion. This doesn't seem likely.
30% of 70 is 21 and April 2011 is about 86 weeks ago. 21*86 = 1806, so a rough projection of 1876 guides. The vayable website promises "2000+ tours", which with roughly that amount of guides with that projection actually makes sense :)
Thanks for the link.
