How can I view the list of people who have me in their circles on Google+?
Another way to see at least some of the Google+ circles you are in (larger, public circles) is using the Public Circles Database- though this definitely doesn't cover the more quotidien circles (e.g. your best friend's friend list probably won't be in here).
You'll need your 21-digit Google ID number:
From there you can search using your Google ID
