This is not meant as a review of 8apps but more like a notice to people searching for a solution. Read a good review here.
8apps is social networking for productive people. It’s not only meant to facilitate productive people to meet but also work online thanks to 3 available applications with 5 others coming. The first three applications are Handshake – for social networking, Orchestrate – for task management and Blueprint – a brainstorming application.
It is still in closed beta but has some potential because it keeps it simple. Unfortunately you can only join by invite.
