From Mikel Maron’s ‘the World as a Blog’ site (thanks’s to Marc Canter for tip) we get the following:
“What? Real time and updating display of weblog postings, around the world
How? Weblogs.com + geocoding + RSS
Is it really real-time? Nearly! Weblogs.com updates about once per minute. the geo-blog poller checks about once per minute. and flash checks in with the server about once per minute. so at worse, it’s 3 minutes in the past, at best 1 minute.”
