The Ubuntu Software Center will reach the 3.1 milestone sometime before the new year and according to the Software Center Wiki it will gain a software review feature. Users will be able to rate and review applications in the center.
=== December 2011 ==
We plan to release Ubuntu Software Center 3.1, with one new feature:
- Rating and reviewing software, and seeing ratings and reviews submitted by other Ubuntu users.
Of course the best part of the news is that this will land in Ubuntu 10.10 and you won’t have to wait till April to try it out.
