Such a scoring mechanism sounds useful at first but on websites like Reddit it would likely cause puns, cultural references and such to be even more dominant than they already are, as those are most likely to be similarly appreciated by "normally-disagreeing people". I could only see it add much value on heavily moderated/high-effort sites like HN, where there's much less need for it in the first place.
