I have been working in F-Spot sometime after the GUADEC in my return to Mono world after half and a year not coding in C#. The return has been very nice, I love to program in C# and F-Spot is a very nice program.
I have being working in implementing the photo duplicate detection system (duplicates video-demo), and the import from Web Gallery and Flickr web photo databases (gallery video-demo and Flickr vide-demo).Update: The video URLs have been updated to point to a site with more bandwidth.
It is cool to see in the maillist some activities and new developers coding things, in special the licenses support in F-Spot so you can specify the license you want for your photos, and I hope, use it in the export process to Flickr, Web Gallery, Original and others. The Creative Commons licenses will be the first to be supported, following Larry Lessig plans about supporting these licenses in the tools we use to create and manage contents.
In the July edition of GNOME Journal you can find a nice article about F-Spot if you want to understand the current state of the art of the project.
