I've actually done every single one of these things. lol Apparently I'm a "Master of HIVE". :-) It doesn't feel like it though. There's still so much out there to see.
One thing I might have him do is check out a couple/few different front-ends (LeoFinance, SplinterTalk, ONEUP, etc) to see what else is out there and give him examples of the different communities/tribes available to become a part of if he wishes. It's nice to have a smaller, more focused community to follow. Just a thought. Very good list!
You are indeed a master of HIVE... but that's different than being a master of Hive. HIVE is the token. Very few would be a "Master of Hive"
