The Geobloggers website noticed today that Google have started using Flickr photographs in Street View.
When you open Street View in Google Maps the 'User Photos' option often appears in the top right hand corner. If you select this option you can view photographs of the same view from Panoramio, Picasa and now from Flickr.
The User Photos option includes a neat 'Photosynth' type experience allowing you to navigate between the different user photographs of the view. This is definitely now enhanced with the addition of geo-tagged pictures from Flickr
