StumbleUpon is that you?
Jokes aside, it's really nice and I can totally see becoming addictive. Kudos to Kagi team for an other user oriented product. (as a side note, I am using Kagi daily and i didn't know about this tool)
Im surprised nobody has mentioned cloudhiker which is made to be like stumbleupon.
SU was amazing. Stumbling upon Ze Frank? It was internet gold!
Yes, SU was fascinating at the time. I kind of like this style of exploring the web; it gets a bit addictive, you spend hours on it but end up finding interesting content and other stuff that you wouldn't otherwise.
