Yahoo! has acquired IQ Engines and has rolled it into the Flickr team. The IQ Engines team will focus on improving photo organization and search functionality at Flickr.
“At IQ Engines, our dream has been to transform the way people search and browse their photos by helping to process them intelligently. We are excited to take things to a global level with one of the most widely used photo services in the world,” said the IQ Engines team on their homepage.
IQ Engines is no longer supporting new customers. If you have an account with IQ Engines, you can use it until around late September 2013.
