Cool! This is a feature/service I wrote down as a concept more than a year ago. In my case I would like to receive a digest (in a email for example, but this can be a note as well) with the latest popular content from my followers (+ their followers to discover new content). I already use the 'hot' feed in nostr:npub1n0stur7q092gyverzc2wfc00e8egkrdnnqq3alhv7p072u89m5es5mk6h0 where you also can change the hourly interval to check.
