Hello. I'm curious about methods for finding out why subscribers to a
site stop visiting that site. For example, imagine that I have some
social networking site, and I notice that some subscribers (some of
them new members, some old) simply stop visiting it. They don't cancel
their accounts, they just stop showing up.
How might I discover their reasons for dropping out? I imagine that
surveys can be automatically sent to people who don't log in for a
specified period of time, but I'm wondering if others may have
developed user research methods that would be less potentially
irritating to the users.
