This is a feature that we are not too happy with. We built it very quick and dirty just before our launch in 2015 and never really revisited it. It returns some pretty weird results sometimes and is not on par with our other discovery features today.
We decided not to remove it from the product because we know there are fans of the screen, but we aren’t looking to attract new users to the feature, so we gave it less prominent billing than before.
I think at some point we will give it some real love, re-approach the same goal with our increased capabilities and do a better job. But for now, it’s where it is.
