As I (briefly) mentioned in the original post, I'm running a few sites similar to the one I linked to, and only used FrostChat as an example.
What I'm most concerned about is if I'm effectively figuring out which product idea is the most viable using this method (adwords + crappy landing page + comparing which landing pages get the most email addresses). I wonder if zeroing in on one idea to iron out all the kinks (like the language usage issue you brought up) would yield better results.
