Thank you for the contribution. It has been approved.

<p dir="auto">Btw, I have a couple of ideas about this post: <p dir="auto"><strong>Node issue <p dir="auto"><code>stream = map(Post, blockchain.stream(filter_by=["comment"])) <p dir="auto">This shouldn't work since default node defined at steem-python is <em>steemd.steemit.com and it's down for a while. So, if you make it compatible with the jussi or another public node for the potential readers trying out the code, that would be perfect. <p dir="auto"><strong>Mentions <p dir="auto">We can use <code>post.get("json_metadata", {}).get("users") to get mentions. I am not sure twitter username regex has a full compliance with steemit blockchain's username restrictions. Are there any specific reason to use a regex pattern? <p dir="auto">Great job on the series!
