Full time old media critique Jeff Jarvis is not happy about Google's SideWiki, an addition to Google's Toolbar that lets you comment and annotate web sites.

Google is trying to take interactivity away from the source and centralize it [...] It takes comments away from my blog and puts them on Google. That sets up Google in channel conflict vs me. It robs my site of much of its value.

Bad bad Google. Apart from the likeliness that Google's SideWiki is just going to be one yawing niche that no one cares about, the idea that bloggers or anyone control any conversation is just sleepwalking babble. Louis Gray nails it:

Let's stop kidding ourselves. The battle for control over conversations and the silo of discussions is done. Any blogger who believes that they can control the conversations and prevent discussions in far-flung social networks is deluding themselves. And yet, every few months, a new innovation, be it comments in Google Reader, or something like this, freaks the old guard out. [...] Conversations have moved to where the reader wants them to be - and the best content creators shouldn't care if they get to have conversations on their content in any of these networks.
