Kutano, a browser add-on developed in Burnaby that shows you Twitter posts linking to the Web page you’re viewing, is now being touted as “the very first Google Sidewiki client ever”.

Before Kutano added its nifty Twitter features in August, the Firefox and Internet Explorer extension allowed users to carry on discussions linked to the subjects of Web pages.

On September 29, a new version of Kutano, which pulls in “high quality” Sidewiki comments, was released.

A post on the Kutano blog offers some details:

The advantage of this new addition, aside from being able to collectively view web page related tweets, Sidewiki and Kutano comments in one place, is that Kutano will also allow users to respond to and start interactive discussions around comments made in Sidewiki. Currently, Sidewiki comments are not threaded and there is not yet a way to respond and engage another person that commented on the web page. Additionally, there is not yet a way to have multiple discussion topics on one page. But using Kutano, people will be able to engage in more conversational and topic-varied discussions about each web page using Sidewiki comments as well as existing web page related tweets and Kutano comments. As can already be done with existing Kutano discussions, users will also be able to tweet out entire discussions as well.

Additionally, in the future we hope to allow replies and Kutano comments to feed back into Sidewiki, but currently the Sidewiki API does not allow it.

If you missed the launch of Sidewiki on September 23, it’s a feature of the Google Toolbar that lets you post and view comments relating to the Web page you’re looking at in a browser sidebar.
