But what can we learn from tweet stream analysis?
• Tweet stream analysis could be very powerful with the proper tools
• Unfortunately, I don’t know what those tools are and don’t have the API to @mikekirkwood’s brain. So this deck only raises questions…
Can we learn the community’s interests or priorities from most common words used?
• Health (738), Patient/Patients (443), Docs/Doctor (323)
• Is it a good sign that “patient” was the second most tweeted word?
• Use of “data” and “info/information” is good, but what words should be present or bigger? “community”? “design”? others?
What can we learn from the way people use specific keywords or phrases?

What can we learn about our Health 2.0 network?
• Can we map the Health 2.0 community on Twitter via conference tweet stream analysis?
Note: Chart is not actual Health 2.0 network
Can we identify individuals responsible for keeping the conversation going?
• Individuals who were most often sent @ replies
Note: Only considered @ reply if @name was placed first in tweet
