Last night I had the opportunity to demo Landmarks: New York to the Location Based Apps meetup in New York. It was a great crowd, made lots of good contacts, and the response about the app was positive.
The session review is here, and my presentation is shown below (hint: click the View full-size presentation button at the bottom right to see the slide-to-slide animations):
The meeting featured SimpleGeo, which is a great service for location based mobile apps. We may incorporate some features and/or data using SimpleGeo in the future.
