/r/MildlyInteresting has captured the intrigue of over 19M people, so it goes to show that the content is more than just a little bit interesting.

Bored Panda spoke with one of the moderators, RedSquaree, on the continuing success of the page. They said, "I think we've done an amazing job of curating a subreddit that is still niche despite being hugely popular."

"The content is roughly the same today as it was almost a decade ago. Most subs change (for the worse) as they grow, but we've kept things mild—just the way people want it," they explained.

It's hard to define what makes something 'mildly interesting' but in my opinion, there’s a certain theme running throughout. The images shared usually go against the grain of what we consider as “normal”. Or, they highlight some bizarre coincidence that we would never have expected.

However, everyone sees it differently. Since RedSquaree has been moderating the page for some time, I asked for their views on the secret formula behind the photos posted and how they would define them. They said, "Everyone probably has a slightly different interpretation or idea of what is mildly interesting." But they believe that the concept of relatability is most important—it has to be "nothing spectacular but something novel".

But this can also make it difficult to moderate the content being posted on the page. They explained further, "Sometimes we see users post to /r/mildlyinteresting first (because if they didn't, it would break rule 3 of our page). Then, they go on to crosspost to /r/damnthatsinteresting. And we're thinking to ourselves, '/r/HolUp, it can't be both'."

So, should the content be strictly regulated before posting? RedSquaree doesn't think so, at least for now. They said, "Many people have recommended we make a Rule 7, so content must be mild or it gets removed. But it would be so problematic to enforce that we haven't gone that far... yet."

They also told us about their personal favorites handpicked by the moderator team. RedSquaree said, "We have a 'Quality Post' link flair which we use (sparingly) to tag on submissions we find particularly mildly interesting. Everything we've marked 'Quality Post' can be considered officially mildly interesting."

When we’re so accustomed to seeing something in one way, our thoughts are suddenly shaken up when it suddenly appears differently or juxtaposed with something else. It’s a great reminder to rethink what we know and open ourselves up to new possibilities. But there’s a reason why we build these cognitive biases in our minds. 

A research paper called the Theory of Cognitive Pattern Recognition seeks to find out how and why we build these links in our minds. The paper defines pattern recognition as “a process of inputting stimulating (pattern) information and matching it with the information in long-term memory, then recognizing the category that the stimulation belongs to. Therefore, pattern recognition depends on people’s knowledge and experience.”
