Google follows Currents launch with activity-recommendation tool Schemer and face recognition on Google+

Following reports from LeWeb that Google has been working on expanding its location-based products, the company has quietly released Schemer, an invite-only web application designed to help people explore both new and familiar cities.

In line with Google’s promotion of Google+ as a central hub for all of its products, the news was announced there by a self-described “scrappy group of Google engineers who wanted to help people do fun stuff in the real world.”
