Maps is just so much closer to the ad business than all those glorified ICQ clones and B2C experiments. The traditional web ad isn't terribly attractive for local businesses, but with Google maps effectively filling the role that yellow pages directories used to have, small businesses seem almost desperate to throw their money to Google. And Google carefully keeping maps from becoming a cacophony of virtual billboards only seems to make that urge stronger: "if we can't directly pay for ranking, maybe buying some other Google ad products will make the algorithms more favorable". The two sacrificial offerings comes to mind. Maps must be a core strategical asset for Google, because the aggregate ad spending potential of all those small businesses is huge, even when you are Google.The chat apps etc are insignificant compared to that. Maybe they really are just Google-scale coding katas to the organization.
