I'd like to say that UX is not the best, the gray circles dont make enough sign that it's something you should use. So I suppose just putting the link with cards to the bottom of the page will work better from perspective of views, rather those native feature.
It seems like the design isn't fully implemented yet, a data-preload-image tag is used for each circle, however this doesn't look it does anything at the moment.
The great thing since going open source, is we as a community will be able to help drive this, so feel free to check out the repo, and if you can/want add a P.R or add some comments!
