WordPress allows me to include a geotag in my blog posts, but so far it is only visible when I edit the post (see image), not on the actual blog. WordPress say that there will soon be support for making the location of posts visible on the blog.
“Where is public geo data exposed?
Geotagged posts get marked up with the geo microformat, geo.position and ICBM meta tags, and GeoRSS and W3C geodata in feeds. All of this stuff is “machine readable”, not “human readable”; it’s hidden from view.
We’ll soon be launching a bunch of human readable stuff like theme integration, widgets, shortcodes, maps, etc.
Also, geotagged posts and profiles will be searchable in the soon-to-be-launched WordPress.com Geo Search.”
