Yeah, and the interesting thing is that right now Steemit.com is the primary way to connect to the STEEM block chain but it isn't to say that Busy.org or Steepshot, Zappl or something else isn't the app that catches fire and goes mainstream. So those dev teams could utilize a different Ad Revenue Strategy or promoted content strategy in the end and make a ton of money off of it. In the long run though we are all "share holders" of STEEM so whatever application goes mainstream it doesn't matter. We are all catching the ride!
I can tell you this. The possibilities are endless and this is seriously an unbelievable opportunity from so many angles.
The more I have learned about crypto currencies over the years and the more I see from the STEEM ecosystem the more confident I am that we will get rich if we play this out right.
