Well we’ve all been able to geotag in Flickr, but according to this screenshot in the GeoTagging Flickr Pool, we’ll be able to do it natively. I don’t see it in my Flickr menu bar, do you? An astute poster points out a gap in the code that might indicate that they will be rolling it out very soon.
Update - Looks like TechCrunch has some analysis on the issue.
Update 2 - Geobloggers doesn’t help at all.
