I’m not sure if there’s much of a blog here beyond the screenshot, but take a look:
As you can see, all of my contacts in the O’Reilly group have either voice or video capability. Thanks to built-in mics, cheap webcams and iSights, etc., we’ve gone from multimedia chat as the special case to multimedia chat as the norm.
One other thing you might notice: four of the six contacts have the “multiple” icon, meaning they’re on Macs running Tiger. I knew that lots of O’Reilly people were Mac fans, but wow…
Are most of your buddies voice/video enabled?
