The people sharing your posts are all Quuu users, who have selected that they're interested in sharing content from the category to which you have submitted your content.
They will share your submission via whichever social networks/profiles that they have connected to their chosen scheduler - the content will be shared at random by the subscribers over the course of the submission's time in Quuu.
At the moment, one of our most subscribed categories has over 4,000 people sharing its content everyday.
Amongst the people sharing your content will be key influencers with tens of thousands of followers and verified accounts, but anyone can subscribe to each category.
The important thing is that they’ve all declared that this is something they, or their followers, are interested in!
