I think slashdots also most useful for if I recall, basically no ability to vote.

IE If I remember right, as a lurker you get no votes. You basically have to participate, and if you get votes on a post, you then get a handful of votes you can use on others. I do wonder how a system like that would work on other sites. If a modernized form of it could work on a reddit like site etc… Would on the surface appear to be a way to counteract bots, but also run the risk of say one bot getting votes and automating a circle jerk with it’s clones.
