We've all hash-tagged "#Nofilter" more than we care to admit. Instagram's Kevin Systrom and Mike Krieger, co-founders of the app that's revolutionized photo-sharing, will hold a public talk with Kevin Rose of Google Ventures under that same heading. The conversation will dig into the app's success among its 100 million users, as well as Instagram's place in the social media arena — particularly the buzz around its $1 billion acquisition by Facebook and the heightened security measures instituted last year. Prior to the public talk, there's an intimate reception with the founders. We know we don't have to say this, but make sure you Instagram it.
