Who says Google doesn’t care about standards? When playing around with the RSS feed from Picasa Web Albums, I was pleasantly surprised to see full-blown GeoRSS GML for the geo-located items. In fact, they are recording both an Envelope and a Point for the photo. I don’t know where the Envelope comes from, because the UI only allows you to specify a point, but oh well.
Now I’d just like to know why they are using RSS 2.0 with little bits of Atom sprinkled here and there…
