Are there people out there who read this and realize "oh crap, I interrupt too much," or "huh, I should try to be more aware of the other person's interest level before infodumping on them"? My hunch is that people who might genuinely benefit from these suggestions are, to put it bluntly, generally too poorly socialized to even recognize that their behavior could use the adjustment.
A demographic I could see benefiting more from this kind of thing are the obsessive-optimizer class of folks who interact with others in a cynical, How-to-Win-Friends kind of way, and who see social interactions with fellow humans as something to be min-maxed. I'm sure those people are over-represented on orangesite, so this might be controversial, but I don't think that doing an intentional post-mortem on every social interaction you have is any way to live.
