Feedback on my startup (iPhone related)
jiggity: clean interface!  I think one thing that might be nice is to do in-line taste matching.I didn't bother to really answer the tastes section.  When it says OPTIONAL for sign-up sheets, my motivation for filling them out drops to zero.  This is a concern, because the user experience is directly proportional to how context appropriate it is to the user.The site presented a list of games that didn't really interest me.  As I was checking "not interested" down the apps, I quickly lost interest in the recommendations, thinking the engine was broken.Perhaps when the user first comes on, you can offer the top apps from different genres.  Depending on what the user clicks on, then you can hone in on what user's tastes are, instead of requiring the user to explicitly list them out.Third or fourth click in, you might have some unobtrusive way to ask, "We notice you are enjoying PRODUCTIVITY APPS would you like to add that to your tastes?" The idea is to make the browsing and learning as seamless as possible.  (I have http://likebetter.com in mind)
