What I find interesting are entirely new approaches to the interface of search. What happens when search is no longer driven by the command line and the blinking cursor? What happens when, for example, your query is informed by where you happen to be, or who you happen to be, or what you happen to be doing at the time of the request? To explore these ideas, it’s best to step outside the current box of a web browser on your PC, and think about mobility.
As Battelle says in his announcement the themes will look familiar to folks who’ve been following search for a while, but it should be an interesting series regardless.
