Everyone’s always buzzing about ‘curation’ and how it’s changing media, business, everything. But other than serving as a nicer synonym for “news aggregation,” what’s the big deal about curation?

I’ll get to that. But first, I want to tell you about my right shoulder.

My right shoulder is terrible. It won’t play ball, quite literally. I injured it for the first time four years ago, dislocated it for the first time three years back, and it’s never been the same since.

Today, I can totally raise my arm above my head — I just double-checked — and can kinda sorta play basketball. I ought to be doing my strengthening exercises at least a few times a week, but I lost the paper describing all of them. And that brings us back to curation.

In May, I wrote about Postwire, a Pinterest-looking site created by Boston-based Visible Gains that allows users to share private pages of curated content. From that story:

They’ve built up a following with personal trainers and physical therapists, for instance, who want to share customized content like video with different customers. I know from having done physical therapy that getting a paper with some exercises circled isn’t a great user experience, especially when I inevitably lose it. And Daniel told me the therapists love it because they can watch the analytics to see which patients have viewed the videos.

Though HIPAA regulations keep Postwire from sharing the pages physical therapists have created for their patients, the team did send me a page they created, full of testimonials and some actual exercise videos. And it’s not hard to imagine a page like this customized to me and my shoulder issue.

To underscore the value of curation in this process all one has to do is search YouTube for “physical therapy.” There are lots of videos on there; it’s finding the right ones that’s difficult.

Of course, I’m not suggesting that physical therapy will ever go 100 percent remote (in part because more serious injuries require dramatically more intensive PT), but the Postwire/PT example is instructive nonetheless.

The point is, is that the Internet allows medical experts to function as curators, just like the journalists who’ve discovered they can add value by sifting through content and helping their readers find what’s most valuable to them.

I don’t need a physical therapist to explain every exercise to me; I have YouTube for that. But I do need one to help guide me to the videos that are both credible and appropriate for me.

It’s time for not just physical therapy, but the medical community more generally, to learn: curation is king.
