It's how I am now browsing the web: Google Chrome browser. A ton of Google Chrome extensions. A Google+ header. A collapsable bar of all of my bookmarks.
In reflection, it is pretty interesting. Speaks to how large a role Google and Chrome play in my web experience. And (I think) the opportunity Facebook has to influence my web experience with a toolbar / souped up extension / browser / etc. Their reach on and off Facebook is wide enough that it just makes sense.
