Congratulations to Multimap and in particular its founder, Sean. Twelve years of hard work, sensible management and innovation has come to fruition. I’m pretty sure this will be good for Multimap – it would be great to see its excellent geospatial capabilities and fully-featured API combined with some of the cool aerial stuff in Virtual Earth (whose API is terrible by all accounts).
On a cautious note, I hope Microsoft treat their new employees well and with the respect they deserve. Multimap was a great place to work, especially in the early days and once the teething problems of expansion were overcome. I made many good friends there and I still believe Multimap is the best out there for hard core mapping requirements. Good luck all!
