Anyway, when I re-read Idoru, I wondered why we don't really have anything like its proto-cyberspace. With its Walled City, a distributed common virtual world. I can see why the matrix of Neuromancer doesn't really make sense, but having played enough mmos in the intervening years, I'm a little surprised Walled City or something like Snowcrash's Metaverse isn't a thing.
It seems like if the infrastructure for it existed, the Reddit crowd et al would build it out in no time.
We've got half-assed things like Second Life, and I think a lot of Minecraft's appeal is from that same strain. But nothing that really works properly.
It just seems like something that would actually happen eventually, it seems like the demand is there.
The issue is that, as far as i know, geo-location (GPS at least) has a +-10 meter precision, so placing content at a specific spot is, fuzzy.
ps.: by placing content at a specific spot, i mean grabbing the latitude/longitude/height and possibly direction from the device and allowing anyone around it to see it by pointing a device (smartphone/tablet/glasses) there.
edit: of course, the precision is really an issue depending on what your'e "tagging". If you're adding stuff to a town square, +- 10 meters don't make any difference :-)
If you've never heard of any of them, perhaps that's because in practice it's not as great an idea as it sounds.
Imagine being able to create content only visible either through an app's camera or these kind of glasses. Like "Second Life"but on the real world.
"Placing" notes, pictures, videos for your friends or public at certain places; 2/3D objects like arrows pointing at that awesome coffee shop.
Actually thought hard at implementing a prototype (for Android) but my current skills are under par.
