This is completely useless now that Google+ is dead (since 2019). However, as somebody who used Google+ back in 2011, part of the attraction was that the people who liked Facebook weren't on Google+. It was a good forum for geeks, techies, artists, writers, and musicians until around 2013 or so when Google decided to make all of their stuff part of Google+ (including YouTube).

It was a "ghost town" from a marketing viewpoint, but it was my ghost town.
