My work day starts when I wake up and ends when I convince myself to go to bed. Much less of my communication is face to face compared to back then. There's the phone, e-mail, messenger, and so on. But there's a lot of non-work stuff that gets injected in there too. Life and work blend together far more this way. And I see nothing wrong with that except that the burden is on me to keep things in check. But with that burden comes the freedom of more flexible hours, locations, and so on. Few of my meetings are repeating, regularly scheduled affairs. That, of course, helps a bit too.

If someone actually asked me "how many hours a week do you work?" I'd have no idea how to answer.

Welcome to the virtual workplace and, in some ways, the virtual job/life mix.
