Google has released a iGoogle plug-in called “What’s Popular” that presents iGoogle users with a service similar to aggregation websites such as Digg or Reddit.

Google aggregates data from Youtube, Google’s Reader and combines them with links that have been submitted by users, resulting in a gadget that displays the (seemingly) best of the web. Users are able to rate the website with either an upwards or downwards arrow – allowing the cream to rise to the top.

Unfortunately a commenting feature is nowhere in sight. Not yet anyway.
