The Ubuntu Software Centre in 11.04 Natty Narwhal will finally have support for application ratings and reviews, a la Linux Mint.
The current prototype (pictured courtesy of OMG-Ubuntu) looks rough round the edges and has a way to catch up with the Mint equivalent, which I like.
Our concern on the Podcast is the process of mediation by which the flame wars between the application tribes ("my Rhythmbox is better than your Banshee!") can be avoided and good qualitiative reviews can be maintained. RC
