I've been missing the old internet. A little while ago I tried to find StumbleUpon and discovered it's transformed into more of a social media thing. I took a couple days to recreate what I thought of as the core StumbleUpon functionality - click button, get random site. And I've been trying to aggregate what feel like unique, individual, not well known sites into my index for it.
It currently gets about ten unique visitors and one or two submissions a day.
