I think ya'll mislead a bit with the twitter extension. No spot to download it given.
But you do say its in the courseware.
"Three extensions activities, things like how to add a Twitter source..."
I downloaded the courseware and dug through the various code and docs. No twitter data source in any of the included samples.
Any shot we can get the twitter data source from ya'll?
