As a case in point, I used this software to create the following slideshow:

Open Source Slideshow – IMA2007 Project Planning Session

based on my conference notes from the informative Project Planning tech session.

The elevator pitch:

• opensource, standards based. Only requires a browser. No costly, proprietary software necessary.
• Authored using only intutively formatted text files!
• A fast, easy way to go from conference notes… to getting the word out!

The presentation above was created using the following text file.

Note: I discovered this tool as a result of checking out Jacob Smullyan’s (from WNYC.org) del.icio.us bookmarks – another case for using existing tools for collaborating as a network.
