Half baked but crispy

In the latest update of the Google Toolbar (IE and FireFox ... not Chrome (!)), Google has just released a new general purpose web-site commenting tool called Sidewiki . There's a video -- on YouTube of course, and several pieces of commentary, some pro, some con and some uncertain. Bloggers are somewhat concerned that it will take comments away from their native comment tools making them invisible to part of the community. Others see it as a spammer's charter. There's an API so presumably aggregation and social sharing tools won't be far away. I've installed and used it to add a comment to this post ... just to see what happens.
