I suggest adding a recommendation engine to the site. Currently, finding new things from people you don't follow is very difficult. You either have to be extremely lucky while browsing the newest submissions section, or be grateful that you are subscribed to a commissioner or eager collaborator. There are not many commissioners on the site, and collaborators, well, they need much more time to complete an artwork than a regular submission. I also sometimes browse the favorites of the people I like, but that is very tedious.
