Is wikipedia becoming too monochrome black & white TV

Wikipedia is a great knowledge sharing sites. It has spread millions of people free knowledge. With current condition wikipedia is becoming more stagnant(interaction) and one way communication medium. Though there are links to external system, articles etc, but it lacks modern IM or Commenting system.

In case I want to modify the context I need to login and edit the content and submit. This seems to be old methodology. With new Jquery and Commenting system user can click particular paragraph add an edit or comment on particular paragraph and user can upvote and downvote.

This idea focuses to bring new social features to wikipedia to become socio-pedia(social wikipedia)
