This is exactly where I see the Hivemind really helping out too. At the moment it's hard to find 'your people'. I've recently noticed there is a small but very enthusiastic fitness community on Steem, but only found them through friends of friends of friends on the platform. Once the Hive is implemented and it's easy to find people creating content on the areas you're enthusiastic about, I think the platform should explode.
I'm sure there are people that only post about certain topics because their followers expect a particular type of content, and with Hivemind I'm expecting that to change somewhat.
Eventually Steem should be right up there in the Alexa ranks, which means our content gets seen by lots of new people, which will encourage content creators to jump aboard so that their content ranks highly on Google as well.... there are a lot of things to be excited about.
