I'm not sure I understand who this is for. The copy reads "Acorn allows you to piggy back off the market leader and give you much higher visibility. With Acorn, the results of a query are shortened to just those apps that do what yours does."

So I can use it find competing apps. That's fine, cut why would a consumer do that? They don't want apps, they want to do something. Seeing a map of a bunch of other apps that are similar to something they already use I think is somewhat useless.

Do people want new apps to do the same thing their existing apps do? Or do they want new apps that change their lives and do something new?? I suspect the later.
