I can't stress enough how much I miss StumbleUpon
StumbleUpon once sent me to a supercut of Lion King, Lion King 1 1/2, and Lion King II, the main edit being that the scenes of Lion King and Lion King 1 1/2 were interspersed so that they happened in the order they actually happened.
stumbleupon not existing anymore can be directly traced to a dramatic decline in my mental health, I could do a thesis on it.
bestie stumbleupon very much still exists its just called cloudhiker now. i use it all the time.
mini compilation of suggestions from the replies:
The Bored Button - "Press the Bored Button and be bored no more."
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."
