Russ has something here:
Okay, I didn’t look this up to see if someone else is doing it, but I was thinking about Moblogging and the idea of real world annotations – where you can mark a space using GPS and then someone else can “see” what’s happening at that space when they run into it with their cool high-tech mobile phone.
I love the idea of tagging a unique number or identifier to a place and then being able to access it later. I don’t know how well little stickers with numbers would be recieved by law enforcement, government, and tree huggers. Damn tree huggers.
In a system set up like this, I’d also love to see many ways to get at the data. Cel phones would be able to access it via WAP/WML, MMS, SMS, etc. I’d also like to see clients for Java-enabled phones and possibly native Symbian-OS clients. I’d like to see XML-RPC, SOAP, REST, and other web service interfaces to the motagging data so that we can get at it in the way that is easiest for any particular situation. (Sorry, it seems that when I get excited, alphabet soup tends to happen)
Laptops on 802.11b would offer a richer interface to the data, possibly with links to or geographical representations of other nearby tags. There would be a tagpop top 40 which would monitor the most popular tags across the globe so that we can see where new and exciting things are happening, and finding out where in the world is ‘so last week.’
You could pop up an interface on your phone to find any tags that are within three city blocks of you. Eventually the tags would cease being little stickers posted everywhere and the technology would fill in with GPS other next-gen phone features.
I’d love to see MoWiki’s pop up, though they’d have to be easy enough to annotate (read: easier and less intimidating than current wikis) and the wholse system would have to be resistant to abuse.
I would claim ownership of the tag at the sub shop down the street and tell people that the pizzas taste great if there’s a line out the door but are not so good when it’s slow, or to get the Chicken Suvlaki on a sub roll, but watch out cause it’s messy. Someone would chime in a week or two later and say that the meatball and cheese sub is a little bland but great for $3.50.
It would be really hard to filter out tag spam. Signal to noise ratio might be an issue.
The idea has tons of potential.
