I've been playing with the beta for a few weeks. The on-boarding is surprisingly delightful. After authenticating with Instagram, you're asked to select 9 photos. It's fun and nostalgic to browse older pics. (side note: this is one of the primary drivers of engagement for Mindie, IMHO: http://ryanhoover.me/post/660420...) It's hard to foresee how engaging the product will be until they have a significant number of users but I love the concept of connecting people through pre-existing content creation (in this case, Instagram photos). What do you think, @abramdawson?
