Recently I wanted to know what online presentation tools were available. I was aware of Google Docs, Zoho, and Sliderocket, but I wanted to see if anything else was available. After some searching, I came across a Go2Web20, which is an online searchable directory of Web 2.0 tools. The site is very easy to use, and I was surprised with the variety and number of web 2.0 tools(apps) available. As an example, using the search word "presentation" resulted in 33 hits. If you love using web 2.0 apps, definitely visit Go2Web20.
