Ill be honest, voting being public is a big deterrent from kbin for me, after having experiences in the past of having people harass me on the assumption that I had downvoted their content.
The risk of being targeted for harassment over a downvote basically cements kbin as an unusable platform for me.
E: And, on thinking about it? It also has me doubting the quality of kbin sourced content. Downvotes on reddit style forums, which this is, work as a community driven content filter. Actively discouraging the use of that filter means higher quality posts are harder to discern. And sifting through more chaff per good post is not appealing.
