At first I refused to play the game of communities, but after a while I convinced myself that they're really a good thing and now almost any post that I share is targeted to some community. This is really a Steem improvement that is quite overlooked by many users.
I'm glad you chose to use them in the end. The best quality of communities, in my opinion, is that it puts together people with the same interests, and if you choose the right community to post in, you will see more users interested in your post than a post on your blog.
Exactly. You said it the best way.
