Findery is a social mapping app from the co-founder of Flickr
Findery members can also create "Notemaps," which are based on certain themes. For example, currently on the app is a Notemap for "Tacos" which details the best Taco stands across the country. "NYC Memory Map" details the recollections of an ex-New Yorker. Members can also enable or disable notifications, which are received when someone has favorited or commented on the notes that they have posted.
The app is a free download and while currently available in English only, will soon be translated in other languages. There is no word on whether we will see Findery made available for other mobile platforms.
