That's a key issue, pb. In less tech-oriented areas, I see a lot lower penetration. But I'm also seeing incremental growth - one person in a company gets on, and then invites a bunch of contacts inside and outside the firm. The networks in the hinterlands are still kind of thin, but they are growing.
