I actually do think you're seeing this trend towards organizations just caring more about their brand and engaging. And so I think Home Depot will want to humanize itself. I think that's a lot of why companies are starting blogs, are just giving more insight into what's going on with them.

I hope that Facebook and other Internet technologies were able to help people, just like we hope that we help them communicate and organize and do whatever they want to every single day, but I don't pretend that if Facebook didn't exist, that this wouldn't even be possible.
