I'm so glad that you settled into telecommuting so well. As you know, I've been working for myself and/or telecommuting for the last five years. I've never really had the experience of a shared office, but I do use Skype a lot, sometimes talking with work mates for hours at a time. The trick is to be disciplined and give yourself "offline" time to either concentrate on a task or just for a break. If you get that down, you're cooking on gas.
