Decoding natural language is almost impossible. You'd have to pick out single words or locations, which can often be taken out of context.
Even if you could, lots of other services do this to some degree already. Ad targeting relies heavily on user preferences (though broadly, such as other sites visited or for example showing specific ads if a user likes a certain page).
How would you market it? I don't really desperately need an app like this right now.. you'd have to convince people to use it.
Do people think apps succeed automatically? Dump thousands into ppi, send out 100 emails to mobile blogs and hope for a review, buy lots of ads targeted very specifically.
I'm a Forrst member and I've followed your little site from the beginning. You have a neat concept but your promotion strategy is pretty bad. I'd also not try to make a profit from day one.
I was under the impression you aren't able to downvote on this site. In the same way this site is Reddit except the fact you can't react negatively to anything (downvote), we now need to do the same for comments.
You either upvote or you do nothing. You either comment positively or you don't comment. Excellent job patio.
