I think at the moment I'm personally most invested in @aftersound content, because of Splinterlands news, thoughts and ideas. He is definitely not overlooked, he is a very well known figure in Splinterlands, I think most people know who he is. He also does content outside of Splinterlands too.
On hive he mainly posts his youtube video links which are the main core of his content, but he also adds some things in form of blog text too.

Also for someone who is relatively new on this platform and creates quite good content is @foxkat . I know her in real life personally and I think she would love to gain followers on her blog page. She doesn't post that often, but whenever she does, I enjoy the posts.
