The relationship between my life and web use is kind of complicated. I have three different browsers open throughout the day.
1. Chrome - I use Google Drive/Docs for almost all my project work, along with Google Plus, Google Hangouts, gmail etc. It seems to make sense to use Google's browser for this.
3. Safari - I use this for everything else, as shown in the graphic here. Google features strongly for search, but aside from that there's quite a big long tail.
