Great article! It's really nice to have such a posts from developers here from time to time...

By the way, I see you are using eSteem Surfer 2.0.1. There is 2.0.3 already ;)

P.S. You can use this image as a post cover if you like to make it unique. I believe @esteemapp will resteem that so posts in the feed will look less similar with different images.
