Yes, we realized that.

At the moment we're not factoring that into Community Rank. We tried but there are simply too much challenges that it's not feasible when looking from the birds-eye view on the whole cryptocurrency industry. (ie. How do you compare a Steemit/Busy/Esteem user to a Twitter follower ... etc)

This might change in the future though as more people start using blockchain based social media.. who knows!
