My philosophy is closest to Tami’s quote above — all 3 are a mix of business, friends and family and since I don’t feel a strong need to segregate the various parts of my life too heavily it tends to work for me. Occasionally I am delighted by conversations and interminglings happening on my networks between folks who might otherwise never have crossed paths — a former business colleague gets into a discussion with an old friend from high school about something I posted on Facebook, for example. As a fan of serendipity and unexpectedness, I often enjoy those interactions between people who might not have had that same opportunity to connect in the f2f world.

I also enjoy seeing TweetDeck messages go by in very much random topical order — but then, I am someone who has literally had iTunes on random play constantly for about 5 years. ;) If and when needed, Facebook, FriendFeed and TweetDeck allow me to sort contacts into groups so I can follow specific buckets whenever I wish.
