I wonder if a poll could be done on Hive asking members when they joined and how they found out about Hive?
Strawpoll does free polls, and you can embedd it into your next post as part of some end-of-year market research.

List as many options as you can in the poll: reddit, facebook, twitter, bitcointalk, tiktok, friends, family.
