Show HN: seekr [StartupHacks hackathon, London]

Background. We're a diverse team of students and young professionals that has just spent a productive weekend at StartupHacks London building seekr [1], and we'd love to have HN's feedback on it.

Product. Put simply, seekr is a service (and iOS app [2]) that lets you find interesting events around you. Our aim is to figure out in real-time what's popular. By analysing publicly available social data we can avoid relying on 3rd party services, and also create some valuable data of our own. We also use the metadata to improve event detection accuracy and identification.

Mobile. The iOS app can be used to submit photos (together with a "mood" rating) and to browse a map that displays photos grouped in clusters, their size being an obvious indicator of popularity.

Platform. seekr is effectively a platform - by making our APIs public we can allow developers take advantage of the analysis we perform on the data. Our technology stack can be seen here http://i.imgur.com/t0gEYq0.png
