Thanks for your reply. The reason I say that Steemit is getting more popular is from the Alexa rankings - putting now in the top 11,000 most visited websites in the planet - that's a pretty impressive feat in just a few months. Of course it could also be a popularity bubble that will burst especially as there could be a good number of people who are only on Steemit due to the financial incentive.
It will be interesting (from a personal view) just how much people interact and whether the quality content really does filter to the top or whether the scammers and spammers will find a way to take Steemit for their own advantage.
Ultimately, only time will tell , but whilst on that journey, as a speculative investor, it will be interesting to see if I/we can "work out" where it's all going.
