Businesses are going to get smaller and more local in the future, if they don't get globally huge. We will find it harder to know who is reliable and who isn't, and we won't necessarily know who does what best. Who is going to help us navigate that landscape? It won't be enough to just find local businesses, because you won't know their reputation, and a simple rating or review system isn't much better because you can't necessarily trust the ratings and reviews.

PS - We need a reputation system we can rely on to evaluate strangers.
PPS - I don't think such a thing will actually happen.
