Deja Mi is described by the developer as:
... your best app for Exploring & Discovering your city and the world around you.
I started using the app. At first, it was nice seeing photos from around the area. But after seeing the tenth photo of a sampler from Triumph the novelty started to fade.
From the Foursquare website:
Foursquare helps you and your friends find great places and make the most of your visits. Get personalized recommendations, search for what you're craving.
This is not an Instagram type photo-sharing app. This is a Foursquare type app with an emphasis on photography. The only thing lacking is retailer deals and mayorships.
The app is location-centric. That means that photos are organized by towns, cities, neighbourhoods, buildings etc. You can follow a photographer or a venue.
Deja Mi may be a great app if you live in an area with exciting venues and good iPhoneographers. It sucks if you live near a college town. You will get a constant stream of chest shots of college women and college men stuffing their faces. I don't know how to change location. Perhaps it's buried somewhere in the app settings but for now, I am stuck watching the antics of Princeton University students.
As I mentioned above on Deja Mi you can follow people or locations. E.g. I can follow the Princeton Public Library to see the photos that have been uploaded and geotagged with that location.
The "My Feed" area of the app ( or web site ) is where you can see the photos taken at your favourite venues or the people you follow and their through their uploaded photos and videos. I think it's boring. If I subscribe to the Hoagie Haven feed what sort of photos do you think I'll see? It's a non-stop frat boy eating hoagie feed.
Yes, the app has some.
##Twitter and Facebook Sharing##
You can share your "check-ins" on Facebook or Twitter. Nothing else to tell you.
