I'm using the layer on Google maps and it's not showing any posts around me it just says that there are no posts from my followers and whatnot, I even tried going around Orange County where I am from and there was nothing!
click the icons that then show up on the map as a google talk like icon might need to zoom out if in smaller towns.. only two people in my town on buzz at the moment
when you turn on the buzz layer then an icon in the BOTTOM LEFT of the screen will appear. It looks like a paper with writing on it. Click that and it will show you the most resent buzzez around where you are looking on the map. For example you might be in Miami but if you scrolle over to San Fransisco and press the bottom left button it will show the buzzez in San Fransisco.
