I enjoyed looking at these varied Web 2.0 tools. The puzzle site is fun and I want to play around there more, although that is strictly for personal amusement. I found many of the sites interesting, but not things I would visit or use again. It was helpful for future reference to see the types of tools available.
The site I was most interested in for teaching purposes was the timeline site, but I was disappointed in its features, as it only allows for photos and text, not videos, music, voice over, etc. It has spurred me on to further research, as I hope the perfect web tool is out there for making timelines. Any suggestions?
