Mike over at Blumenthals has an interesting article about the Endoxon aquisition. Thanks for the update btw. Still it’s a little confusing to me. Guess their understanding of geotargeted search is different to what mine would be.
Regarding the correction capability here an interesting article on the blog of Gregor J. Rothfuss the founder of the endoxon mapping startup that Google acquired. And here another one on whats special about their technology GoYellow.
