We all hate Bangalore roads. What can we do about it? Well, the political ramifications of getting BBMP to move their behinds to fix the roads may be beyond technology magic, but we might be able to do something to raise more awareness.
Lets build an Android app + Web app that lets people quickly snap a pothole (optionally add location tags), a short blurb, and post it to a public community feed.
A separate visualization would let you look at areas of the city with the most potholes (or with the most votes(?))
So anyways, this is the gist of the idea - more at the hackday.
