I checked out quite a few ones in various categories, such as mapping, video, retail, and organization on the winners list. Really impressed with the development in 2.0 tools.
I was just wondering how these winners were determined. Take Photos and Digital Images for example, Flickr is featured in this 2.0 course, yet I have been using Picasa, since somehow, the software got installed on my laptop and find it pretty cool! Ditch one for the other? Or I guess it does not hurt to have the best of both worlds.
