Re: What's the incentive for vendors to use this?
"I think Google thinks they are so indispensable for those services that no one would dare leave them, but I don't think the average person would even notice if you replaced Google with Bing for their searches. For the type of searches the average person does they are the same. Here Maps is a good alternative to Google's, and so forth. Google isn't indispensable, they just think they are."
Oh? How about putting them all under one search? How would Bing talk to Here, for example to link a search to a map? Or what about all the metadata Google can aggregate such as traffic data? Last I recall, here's traffic data isn't nearly as robust since they lack scope.
