There are some objective factors like spelling, time spent creating the content, quality of the pictures/text/video, knowledge and expertise on the topic etc and other subjective stuff like opinion of the curator, preferences, expertise on the topic by the curator (for example I can't asses if a painting is good, but we have curators that do) and some others.

The good thing is that we have many curators focusing in finding great content for over two years now so we hope to deliver on the community's expectations.

You can add "verifiable sources" to back the statements made in a post, especially if it contains any scientific topic.

Also if there are lots of comments and real discussions in a post, that's an indicator of interesting content.

Original content, subjective quality by many curators with a lot of experience.

Experience in what? Running a social media business? Genuinely asking

Experience with curating content. That includes:

  • looking for authors all over the chain (by using different tools and methods)
  • judging quality (still subjective but experienced curators have higher standards I guess)
  • and investigating to check for plagiarism/identity theft (which is a hard thing to do, requires a lot of time, and the most important part, btw).

I have seen many curators vote for authors that turn out to be just stealing identity from a content creator form other platforms... and they are not easy to detect cos they are good at pretending. A good/experienced curator is more likely to detect these shady acts even by just scrolling through an author's blog.
