One of the most useful things about Wizi is something I never expected.  I thought my main use would be to keep track of friends to link up for social purposes, or to let my wife know if I'm on the way home, saving me and her all those extra, "when are you coming home?" calls.

But the most frequent thing I do with Wizi is glance at the screen to see where my business partners are before I call them.

If it's early in the morning, or late at night, I want to know if Peter is still burning the midnight oil at the office, or if he's at home with his daughter.  For routine calls, I won't bother him at home, but maybe if he's commuting, or working late at the office, that's a good time to catch him for a chat.

I keep myself visible to all my business partners, too.  At first, I thought it was a little strange to let them know where I was every minute of the day or night, but now I actually find it very convenient - for me - that they can find out where I am at a glance.  If I'm late for a meeting, or on my way, they know.  If they want to call me, they know where I am at the time.  Maybe if I'm at my favorite restaurant, they're going to postpone the call.  And if I'm still at work, they can call even if it's late.

I admit it took a mental leap to set Wizi to show my location so often (and sometimes I do turn it off), but now that I've done it, it seems completely natural, and I wish more of my friends and colleagues used Wizi to find me.
