On the "b2b" thing: I think that's a mischaracterisation. It's not "to business" specifically, it's to anyone who wants to make use of the data. There are already OSM-powered consumer-grade mapping sites for particular verticals (I run one for UK cyclists, http://cycle.travel/map) and more are on the way.
But it's not true that osm.org goes out of its way to avoid being a consumer service. It may not be the prime focus (and nor should it be) but there's a lot happening on the user-facing side of OSM: a significant redesign last year, lots of stylesheet improvements underway, and routing going live in the next couple of months, for example.
