It's already profitable, but not profitable enough to fully reward the time spent on it. I would like to see it move toward becoming a community-driven project, with people contributing their own curation commentary, and then talking to each other about why different posts were selected and what it means to create good content.

Ironically, that will initially make it less profitable (some of the promotion costs will be indirectly passed through to contributors, instead of recouped as profits), but it's more a labor of love.
