The Hustler
Mhh, forgot about that one. Guess those have decreased on Hive compared to Steem. But there still indeed are.
Did also forgot the role as advertiser and client.
The advertiser does reblog a post after upvoting it, so that it can generate more value.
The client, well we all are also clients. You do write for your clients and if they do read they are a client, a client which could turn into a curator, advertiser or something else.
There are even more roles than I did imagine, but the article was already long enough. I do have some inspiration for next week :)
