Thanks for the great feedback since the launch of the beta two days ago!
One change we plan to make fairly soon is improvements to the Discover page, so that it is easier to find content in general across the network. We know that some of the content has been rather immovable on that page, which has made it hard for newer content to stand out.
Thus, we're tweaking our "featured" formula to (hopefully) loosen things up a bit, but also adding more options for discovering content, via separate trending, quality, and "recent" filter options on that page. And, of course, if these changes are still not quite right, we'll continue to evaluate and improve things until we find the right mix.
I do expect that just having more ways to filter content across the entire network will make it easier for everyone to find new content.
I'll let you know when these changes are in place.
