Not only can I already visit Times Square in real life, I choose not to. Ditto on the more branded, corporatized, ad-infested portions of the internet (ie: the "downtown internet" approved by official, polite society).
Many scifi novels (insofar as Snow Crash can even be called "fiction" rather than "prediction" these days :-() are written to make fun of wacky technologists and our just-somewhat-off-target ideas, you know.
Now, to end on a zog note rather than zig or zag, here's an idea: someone figure out the massive-game or VR equivalent of 4chan. There's something people will actually want to use. (For all the official disapproval from all sectors, 4chan and 2chan are massively popular and influential. They are offering something users want: anonymity, obscurity, simplicity, and freedom!)
