I agree Google Maps has improved, but I’m not convinced it was directly because of acquiring Waze. Waze UX has dropped so much since acquisition that its almost to the painful point. I also find it’s “user submitted” data (cops, construction, pot holes) has dropped a lot so I feel a lot of folks who were submitting quality data have either left or just stopped submitting as the UX has gotten so bad.

Keyhole is another acquisition in the mapping space that I feel has degraded since being acquired by Google. I was a paying customer of Keyhole and loved it, since becoming free under Google, it’s basically stagnated and some of the features I used are now gone.
