"Bring[ing] everyone else to your pace" by increasing latency struck me as a really nice idea. It suggests an additional feature that could be added to a site like Hacker News, where each reader can choose an update interval, and have news delivered on that interval.
The key is to use a ranking procedure that is appropriate for the interval, so that the reader doesn't get new stuff for that day, but the best over N days (or N seconds -- not everyone is Richard Stallman).
This feature may be silly and unoriginal; but I'm commenting on the internet so I thought it fit.
[Edit: when I said "delivered" I didn't mean by email! Just "updated".]
