I think that's a great approach. Personally I haven't been on social media for a couple years now (for various reasons including concerns over data privacy) but I considered having all those opposing views at hand to be one of the principal benefits of social media - in fact, that was the main reason I stayed on social media as long as I did.

I would say it was definitely possible, it just took a bit more effort. (Since leaving social media I've made a point of reading left-wing and right-wing opinion sites side-by-side. It's very illuminating.)

That said, it does seem like for the average user the tendency is for social media to become an echo chamber.
