And, of course, I try to get in touch with my brother and sister who are abroad regularly by sending them email updates about what's happening back home. I created a family Googlegroup more than a year ago and that's how we communicate with the whole clan. And badminton announcements and other plans are announced by my friends in our Googlegroups as well.
I'm now brushing up on Google Apps for Your Domain - planning to use it for our family as well.
Whew! It seems quite overwhelming to be using so many different products, but it's become second nature. I'm not as techie as my tech blogger or programmer friends, but I like trying out new things and that's how I learned how to use all these products and it's made me a whole lot more productive :)
