I am at the computer science museum in Mountain View at the first part of Mashup Camp where API providers are showing their stuff. There will be a lot more tomorrow, and then on Wed and Thursday mashup folks will be showing off their stuff.
I get the impression that this is a different crowd from the first camps, where most were already familiar with mashups, though perhaps those folks will be coming Wed and Thursday for the main camp.
Anxious to try Intel Mashmaker, which looks good.
Most of my blogging about this will be at WebGuild
