i don’t normally comment on RSS, but i have recently had occasion to deal with two sets of RSS extensions. both extend RSS into the geographical realm, but are lacking test cases so far. so i wrote to the two originators of those extensions, and got wildly different responses. a clueless “shucks” from yahoo, collaboration from the georss community. luckily, the yahoo extension is not causing a lot of damage since they are limiting their own success with their ineptitude.
