Mayfield: IBM and Microsoft are too expensive, but that said, I think there will be a shake out in the Enterprise 2.0 space. I think the larger companies, like Microsoft and IBM, are going to have the cost of their implementations questioned with greater scrutiny than ever before. [Socialtext] is a tenth of the cost [on average] than an incumbent vendor. If you're not just looking at license, the total cost of ownership for these solutions matters more than ever. You're going to have less people to operate and own. You've seen the studies about . In these turbulent times, you need a Software as Service (SaaS) driven model. In that model, you can deploy a tool that will give you strategic advantage without a lot of upfront cost relative to traditional licensed software. You you can rightsize the application for the amount of users you're ready to experiment with until it delivers the right kind of value. It's subscription based, so you're in a shorter commitment than traditional licensed software.

CIO: What did you learn from the last recession? And how will this one be different?

Mayfield: I don't think the pace of innovation in Silicon Valley will necessarily slow down. That's partially because of prior investments. During the last recession, enterprises just stopped buying. It was the fear economy. They only invested in security and compliance. I don't think we're in a period at this moment, where security, compliance and maintenance are the most important things. There are some necessary evils, but I do think technology is about gaining competitive advantage, and right now smart companies will make smart bets in technology. When it comes to intranet and extranet productivity, and platforms that help people innovate their way out of a recession, I think that's a real opportunity for enterprise 2.0.
