Yesterday, I was eavesdropping on a debate about open source vs closed system. I found the debate fascinating because two of the most important contributors to what our search experience might look like live at opposite ends of this debate. Apple is adamant about locking down every aspect of the user experience. Google wants to open it up to any and all comers. The third player, Microsoft, sits somewhere in between. The debate was about who might prevail. I was uncharacteristically silent during all this, because I had to think about it before throwing in my two cents. Now, 24 hours later, it’s time to toss in my ante.
