Currently, there already is an alternative to the trending pages: Curated niche tags such as #photofeed and #travelfeed that are way better for finding quality content than their non-curated counterparts, but the best way of finding great niche content is by browsing the posts resteemed by the curation accounts @photofeed and @travelfeed. I am part of the travelfeed team myself and we hope that when the community feature will be introduced, this will solve the problem with the trending pages.
