I understand that this post was from a year ago, but I still find this useful. I am new to the steemit platform (Dec 2017), and have not actually posted my intro post. No personal posts at all. However, this is soon to change.
While googling on writing a good intro post on steemit, I found this:

which led me here. I truly appreciate this excellent information. I believe I'll accept this post as my guide to go on.
