The Personal Productivity Show #13 featured Brian Dougherty, CEO of AIREANA. There flagship WEB 2.0 product is AirSet. Currently, I am evaluating this to help increase the harmony in my relationship with my wife. It is great when after over 7 years of marriage one of your biggest challenges is knowing when to schedule a doctors appointment or what night I have a meeting to attend, and who's birthday or special event is coming up.
Since I have my own Exchange server at home, sharing Outlook calendars seemed like a solution. However, this solution turned out to be to clunky and only worked with calendars on our local Exchange server.
My wife and I are now evaluating AirSet to help with our scheduling and contact management.
I will keep you posted when I learn more about how this works for us.
