Why do you assume a hobby or interest still has a significant presence on the non-algorithmified open web?

For travel-related hobbies, for instance, there is no longer any kind of significant open-web scene where people just share stuff to help others or because it is cool. (Yes, you can set up your own blog, but pretty much none of your peers will ever see it.) The community might be using a variety of apps beyond your "like 5 websites", but all those apps are designed around phones and minimize text content, and so they are just as pathological as "sites with 'creators'".
