We are in the process of making the default home page the primary community experience, we were finding that the community tab really wasn't performing all that well in the past.
So, you'll be seeing a lot of the community related stuff (i.e. collections, small tiles, large tiles, spotlights, etc) on the default home. Right now it's about a 60:40 on the homepage favoring Premium since that's a large revenue stream for us and allows us to reinvest that revenue in more projects, but with the introduction of the Premium Tab we can start migrating a majority of the Premium series from the home to that tab
And yes, we'll be seeing WAAAAAAY more community banners on the homepage and they'll be rotating at a fairly fast pace to allow us to feature more creators than ever before.
Hope that helps!
