NaN had a strong presence at Hypertext 2009 in Torino:

• Mark's paper What's in a session: tracking individual behavior on the web was nominated for the Best Paper Award.
• Heather presented the demo Incentives for social annotation about the prototype Firefox extension for GiveALink.org, and the tagging game. (Heather is also demoing at SIGIR'09 in Boston.)
• I presented the demo Sixearch.org 2.0 peer application for collaborative web search about the latest release of Sixearch.
• Ben presented his poster on A scalable, collaborative similarity measure for social annotation systems.
