Copywriting has always been a thing, but this doesn't require much understanding of Hive. You can publish your post on any platform with little change to the content.

However, curation is highly platform-specific. There are already a few large curators on Hive who have hired specialists or built up special communities, so it's actually becoming a job. The exception seems to be TIPU which is taking a different approach to curation, but that's why it's often so weird and poorly done (ex. curating a popular whale or orca's post).

Personally, I don't want to become a specialist but I do want to hold my own and be better at curating. Ideally, I want to become great at recognizing great curators. It's much harder than recognizing a good writer (someone who interests me).
