I don't know if you hear these same rumblings, but there are industry people who believe that the web will shift from existing as we know it and morph into a few mobile apps: FB, Twitter, LinkedIn etc. For instance, I had one investor tell me that he would like ReplyAll more if we had built it as a FB plug-in and I had another investor tell me that he thought the blogosphere and content sites would disappear altogether.

You seem (at least in print) to be very even-keeled. Is that a personality trait or have you developed techniques that help you stay balanced?
