A longtime tech exec, Kertzman is one of the funniest players in the tech sector, and was once the font for all the best jokes about Microsoft, back in the day when no one made jokes about Microsoft for fear of digital defenestration.

Today, Kertzman is actually much more serious, focused on the business-to-business part of the Web 2.0 world, rather than the more popular consumer-facing areas into which most VCs have been pumping oodles of money.

While Kertzman was early into the widget trend–in fact, he was the first to say the word to me at a Demo conference where he was showing off the Widgetbox, the widget directory startup, a moment for which I shall never forgive him–his new focus is on companies like SlideRocket, the online presentation application, and other Web-based productivity products like it.

Yes, I swear, SaaS–Software as Service–can be interesting! Really!

We also liven things up with some chatting about too-high valuations and thoughts on the Microsoft-Yahoo takeover battle, as well as the recession.
