I have searched the site but did not see any answers addressing the following question on gathering user reviews:
Specifically, I have read a number of accounts suggesting that there is some number of user reviews that a site needs to have before users are submitting unsolicited reviews. These stories indicate that once the number or ratio is reached, a virtuous cycle ensues.
The theory makes sense to me, but I am trying to figure out what the magic ratio would be for planning purposes. Appreciate any thoughts.
