I agree completely. It does seem really obvious now. But anyone who's had a pre-Google/Facebook online life remembers that you had different handles for diff sites. My aol name was not the same as my underground name, wasn't the same as my regular email name. At first what seemed like a good idea, "mirroring" yourself online as Poole puts it became the bane of people who were diverse in their online dealings. But I look at Google and Facebook as the "establishment internet", there for the masses. And for most people that is fine, they rarely stray from these walled off gardens. But there are still options to be as diverse or "prisimatic" as you please if you look for them.
