> For an illustration: a typical local shop is going put the effort into making sure its information is correct on Google Maps and that their website is indexed on Google; but it's going to put zero effort into updating its info on OpenStreetMap or making sure it's indexed by Bing. If you want info about that shop, you're probably going to have to use Google.

That's a great example, thanks for mentioning it. I'll probably use it from now on.
