This is bad for many reasons, which I’m sure you’ve already thought of. No control. Implied recommendation or endorsement. Inappropriate links. And a lot of confusion for our readers who believe we choose these links or that they will lead to links on our blog related to what we blog about. I’m sure I missed some other bad reasons for not liking this new feature.
Not giving an advance warning while making this an automatically turned-on feature is a bad move, and everything went downhill from here. Make it an option, let everybody know the pro and cons of having it, and this might actually be useful.
Oh. Or you could just make it display related posts from one’s own blog. That’d be stellar.
