I been keeping an eye on Tafiti for a bit now. They use Microsoft's silverlight and done an amazing job with it. http://www.tafiti.com/ Though the downside of them using silverlight is the load time. Really slow. I doubt a 56ker would come along and think their features are cool. Live.com's image search is amazing, but I will say the same thing for 56kers.

Web 2.0 is still here, web 3.0 probably would make hi speed required, but these people are forgetting 56kers now. My mom is still a 56ker, why? She doesn't want to cough a hundred bucks a month just for internet.
