I think just make sure that it is well understood at this point of selection how this pertains specifically to comments alone and that they don't see your rating. Maybe the name of the toggle itself will reinforce this? Could be called something like "X's comment reputation" or something like that? With all of the sharing and voting in different areas, I think the biggest hurdle could be just mitigating confusion over the feature's parameters. Definitely for it though.When viewing a user's profile, you will see a simple rating device, with settings that represent: 'poor', 'neutral', and 'good'. The neutral setting is selected by default. You can opt to change the setting to 'poor' or 'good' if you like.
I absolutely agree with this, and I'm up for suggestions. HTML5 has input sliders, and I am thinking about using that. Regardless of how we label it, I think it will have to have a '?' next to it which brings up a popup explaining the functionality in detail.With all of the sharing and voting in different areas, I think the biggest hurdle could be just mitigating confusion over the feature's parameters.
