The patent talks about a networkable remote controller that can "send a blog posting to a blog," which can be set up to send posts automatically. It includes the ability to comment on the shows you're watching, either by selecting from a pre-populated list or authoring your own. It also mentions posting automatically to microblogging services, which to most of us means Twitter.
The patent was filed April 14 of this year, and the approval process can take some time so it may be a while before this thing comes to market. Nevertheless, it's another stepping stone on the road to socially-enabled television.
