EDIT: ShuZu = no geotags, but lots of interop. AirMe = geotag, weathertag, but you need to photo from in the app which is kinda a pain. Can't find way to upload existing photoroll.
Please excuse massive spam tonight as I look at apps.
EDIT EDIT: Shozu says it will add geotagging soon. Apparently iPhone won't let apps access geotagging data so they have to do workarounds? Maybe I'll keep playing with it a bit longer? Or mofotoblog to brightkite and then iPhoto anything else up later? Death by suboptimal options.
