I came across the term “blogChalking” from, of all things, the American Dialect Society’s mailing list. The basic idea is to standardize on a set of keywords/metatags to make it easier to find blogs in your neighborhood.
After seeing this kind of hard mapping implemented by people at NYCBloggers.com and watch to the rise of WarChalking (in my opinion, an idea that best express, today, the beauty of large public networks), I noticed a possible way: if all bloggers mark their sites with a special sign and geographic information, maybe it would be possible to improvise such searching system.
So I mixed up those ideas to create what I call blogChalking. [...]
It sounds like a have-nothing-to-lose idea, so I may just give it a try.
