Ask HN: Review our startup: Cloudy - let your friends decide

Cloudy is a free iPhone app that lets you quickly and easily ask groups of friends for their opinions. The basic pitch is: "Need help making a decision? Let your friends decide for you!"

We'd love to get feedback on a few specific areas: - The design and functionality of the app - The concept itself - The SMS functionality (that is, how questions are sent by SMS if you pick a recipient that isn't a Cloudy user) - Requiring Facebook for login (we're certainly willing to add a traditional login option, if users seem to want it) - Our marketing copy, both in the App Store description and on the website - Whether we should focus on improving the iPhone experience for a while or quickly move on to Android - Anything else!
