Some Hive powered sites will 'delegate' you the use of some Hive to get you going.
I think, @leofinance delegates 10 hp to start with and they have the most easiest ways to onboard, using a phone or twitter even. I onboarded few friends that way. People are slowly realizing the truth - Centralized social media gave everything free, but when everything is free, then people are the product. HIVE is not very dissimilar in the way that we are the product, but if one can put a little money onto it, then the earning gets better from curation - which these centralized media do not have.
