mini compilation of suggestions from the replies:
Cloudhiker - "Discover the most interesting, weird and awesome websites of the Internet" (not really a rebrand, it's a different person running it but they have the same intention in mind)
Astronaut.io - "These videos come from YouTube. They were uploaded in the last week and have titles like DSC 1234 and IMG 4321. They have almost zero previous views. They are unnamed, unedited, and unseen (by anyone but you)."
Marginalia - "This is an independent DIY search engine that focuses on non-commercial content, and attempts to show you sites you perhaps weren't aware of in favor of the sort of sites you probably already knew existed."
