Nokia and Plazes announced today an agreement for Nokia to acquire substantially all assets of Plazes, a privately-owned start-up company of 13 people with its principal operations in Berlin.

Plazes provides a context-aware social-activity service that people can use to plan, record, and share their social activities: why they are at a given location at a given time, whether in the past, present or future.

By acquiring Plazes, Nokia will be able to extend its context-based service offering with social presence and time-based activity planning features. Plazes adds the elements of "place" and "time" to social networking through features that allow people to alert friends of their activity and location; review their own and others' past activities; share their experiences and make plans with friends, who are then able to respond with comments and suggestions as well as their own location information.
