Limitations
What does it mean to be an active social searcher?What considerations go into seeking help from social networks?
Is social search more useful for certain types of info?Procedural knowledge? Experience-based knowledge?
How is the experience different for search failures?Will we see more cases of social outreach during failed searches? Will searchers exploit all options before admitting failure?
