This is a pared down version of a presentation I have given several times (WordCamp SF, WordCamp NY, NetSquared Montreal) about Global Voices. I've removed the tech-specific slides and added lots of coaching and explanation of what you should say to the "notes" section for each slide.
The idea is that GV poeople (or GV friends) who want to present the site on stage can use this presentation as a starting point for their talk. It has a few key bullet points but also leaves lots of room for talking about whatever you like about GV.
NOTE: I made this with Open Office Presenter and the actual slides are just PNG files I made using Photoshop, so you won't be able to edit the text. You can of course add new slides if you want, just try to emulate the basic style
