Listening to C.G.P.Grey talk about too much stuff in a room making it difficult due to the visual noise. I agree. But I also have an issue with chatter. Lots and lots of people talking over each other bothers me.
The inability to follow all of them is part of what I dislike about them. One-on-one conversation? Sure. A bunch of strangers talking? Okay. Apparently I can tune them out. But, people I know talking? My brain refuses to as easily tune them out.
Maybe one reason why I prefer social media is that I can follow the conversations in an asynchronous multi-tasking way. They can persist longer and cite sources and be better thought out. There are all things I love.
