Yahoo today will tie together a bunch of its properties — Flickr, Yahoo Maps, Upcoming, and Yahoo Local. These are natural and powerful combinations of existing projects and acquisitions, and of course the question is what took Yahoo so long.
First up, Flickr photos can now be geo-tagged via a drag-and-drop interface with Yahoo Maps. Users can make map mashups out of photosets to share with small groups or everyone on Flickr. This is competition for Platial, 43places, Flagr, et cetera.
The Flickr-location combo also brings stalking to a whole new level, with the ability to search by tag, text, time, group, and location — Yahoo’s example is “photos taken at the In-and-Out in Mountain View in the last 20 minutes.”
In addition, Yahoo’s Upcoming.org, previously driven by user submissions, will now incorporate events from Yahoo Local. Flickr will also add links to Upcoming alongside photos tagged for a particular event.
What’s next, Yahoo? How about some presence integration via Yahoo Instant Messenger?
