The “Boo/Dislike” API
Every time I press Publish the post is publicized to Facebook, Twitter, LinkedIn, Path, and Google+, each with their own mechanisms for enumerating how much people like it.
None of those services except Path have a clickable way to dislike something, so if something isn’t great it’s usually met with silence. But sometimes something that is great is met with silence too if it doesn’t drop at the right time, have the right headline, or have the right tone to invite interaction.
