Geograph project. The first 250,000 pictures have been uploaded to Commons at the end of 2009.
Multichil announced that he has received a hard drive with 1,8 million images. He is preparing the upload and welcomes feedback on the batch uploading page. As you may know, a Geograph project has started for Germany and it would be really cool when such a project is set up for other countries as well.
Personally I would really like such a project set up to run in a country like India, Indonesia, Tanzania and have the best of them as featured pictures.
