Not sure I will do this every week but, here is a start.
Recommendations
@crokkoncrokkon 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.
@nafestwnafestw 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.
@sambillinghamSam has great projects around STEEM blockchain also has great shots with his drone.
@muratkbesirogluThis 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! :)
