I am curious how many Droid users are around me, so tomorrow at noon (wherever you are) buzz "Droid" with the mobile app so everyone can see it on the map!
Best method to view buzz is in the maps app. Go to the market and make sure you have the most updated google maps app. Load Maps and press the menu button, then layers, and select Buzz.
You will see a lot of little talk bubbles and that is buzz.
