As an author where your unrelated recommendation just appeared as the first comment, I am NOT thrilled. I spend a lot of time creating my posts and trying my best to answer the comments so seeing yours is like a slap in the face to all that work. It's a message that says "Leave this post and go see this other post".

I'm all for helping people find good content and helping my readers, but this automated process I don't think will do it. You're making major assumptions about what readers want and then coding them. I know you're in alpha so you don't expect your automation to work correctly, but usually projects in alpha don't interact with a production environment.

Having a way to find related posts is a good goal. I would welcome that feature in something like the SteemPlus browser extension. Something that could add the ability to see a list like that without taking away from the work the author put in.
