It could be an idea to get people to get people to record a 10-20 second short video of themselves saying what country or region they live in and something like "I'm for Steem" or "I'm a Steemian!" (or even a more catchy slogan).

It will showcase all the differing regions of the world (every corner in fact) that current steem users come from and could attract many people not using steemit to join the global community.

There could also be group combination videos, encouraging more interesting and varied formats.
