This happens a lot. Usually starts with one popular post about a topic. Then someone explores deeper and finds another interesting article on the same topic, and submits it.

It has happened that I have read about one article and find something related (following links or looking things up) that I find even more interesting and then submit that.

I feel the same. It is not by chance I would think.

Not everything is a conspiracy.
