Show HN: Released My IPhone App (Finderous)

Hi Guys, I have just released my free IPhone App: Finderous, available on ITunes at http://itunes.apple.com/us/app/finderous/id520384764?mt=8 . I would appreciate if you could pass on some comments and suggestions. About Finderous: It is a multilevel location based Q&A app, where users can post questions on city/county/state/country level for visibility according to the type of question.
