"Fast lane" transmission for crappy TV shows vs everybody else (coming soon to a non-neutral environment near you)
Dialup vs broadband (speed determines content)
Mobile web vs deskbound web
Apple web vs non-Apple web*

*Update: Was asked on twitter "What does this even mean?" Answer: censored apps and onerous licensing on "sexy" hardware vs non-users of that hardware
Update 2: Some Apple users assume Windows users have the same unquestioning brand loyalty as they do. My twitter interlocutor used the phrase "your beloved Windows"--hilarious. This person actually reads my blog. The same person accused me of fanboy trolling as a linkbait strategy--like I need Apple zealots reading me. And played the age card - nasty. That suggested a new Balkan category: "old ppl web" vs "falling into manholes while texting" web. And finally, this person noted logical fallacies in the above writing, prompting a reminder that the post is called "sketch of the balkanized web," not "logical, non-contentious categories for easy assimilation."
