I think so a mix is better to achieve more audience. However, there are different points of view about blogging on the Hive blockchain. For example, a teacher will be using the Hive blockchain as a database with long publications to have the information available 24/7. On the other hand, an influencer as you will use the blockchain to achieve engagement with long and short publications ;)
Hive a nice day!
The teacher side is interesting as it brings up something I will write about later - purpose of content.
