Follow Friday is a practice on twitter where you recommend a few people to follow with the reasons on fridays. I have also seen, a couple of times, 
Not sure I will do this every week but, here is a start.
crokkon is not a daily poster but when he posts, he makes sure you will get great insight about the STEEM blockchain with great analysis. He's also a contributor to steem.rocks.
nafestw is an underrated author at STEEM with great projects. He recently developed Deepsteem and generally posts technical content.
It's a new initiative. Expect only good things from that account. There's an amazing team behind it. Have a look at their announcement post.
Sam has great projects around STEEM blockchain also has great shots with his drone.
This suggestion is somewhat for Turkish users. Murat is a great author writing short stories. He has also a couple of english stories but generally posts on Turkish.
Steem blockchain is good and efficient if we interact with real people instead of bots. Make sure you have a look at these profiles and follow them! :)
