Slashdot has posted an article about a site that could be one of the best ways for new ideas to be included in future Ubuntu releases. The new site is called Brainstorm. It has been inspired by IdeaStorm, a site put up for submitting ideas to Dell. Although there is no official announcement on either Ubuntu, or Canonical’s websites, it has been announced on The Fridge website, which is an Ubuntu and Canonical sponsored site.
All you need to do is sign up with a user name to submit your own ideas and vote for others.
Happy Brainstorming!

We’ve built something similar, called UserVoice, that enables any company or community to have a tool like this, but we do a little more to create a market around good ideas rather than just letting everyone vote everything up.
You can check out UserVoice and request your own page (we’re in semi-private beta) at http://example.uservoice.com
