The Yuku service is pitching itself has being message boards for the Web 2.0 world. Do they live up to that hype? Not really sure. They seem popular, but that is not the business I am in. They do have a mighty nice Firefox extension though.
The Yuku Firefox Extension is an add-on that alerts Firefox users with the latest updates on their Yuku profiles! Get notified when you receive a New Message, a New Comment and when you recieve a New Friend Request!
This extension also claims to make it easy to switch between profiles and navigate the Yuku Web site with quick navigation links. Sounds good to me, what do you think?
