== GOAL ==
Leverage the very large number of high quality reviews that have been submitted by Ubuntu users the world over to create a recommendations system for individual users to let them know about other applications that they would most likely love to use, but do not yet know about.

From notes for the UDS Software Center Roadmap session at UDS-P:

== Recommendations ==
 * Feature specification:
 * Helping people find the software that they most-probably will want to use, but that they do not yet know about
 * Discuss more in the server session roadmap.
 * Three places it is likely to appear
  1. Home screen ("Recommended for you")
  1. Category screens (e.g. "Recommended in Games")
  1. Application screens ("People also installed")
 * Potential problems with latency and server load
 * Need to discuss privacy too -- opt-in, all data anonymous
