Excellent job Richard! Those slides are very clean and informative and you got fantastic real life user reports!
Point #1 is very common: lots of behind-the-scenes javascript, buffering, asynchronous requests, facebook chat box and updates, etc.

I was trying to make a mock conversation for the purpose of providing a story backing up the debloating efforts so that end users realize better what's going on. Please, guys, have a look and comment:

Part 1 is an intro, also touching on tiered ISP services. Part 2 would be what bufferbloat is all about. Part 3 is an outro to have the users have a take-home message, also touching on DPI and other evil stuff ISPs do trying to workaround the issues.

You can edit that wiki.

I couldn't post it on bufferbloat.net wiki because I don't seem to have privilege to create new pages so I setup my own.
