Trumba, presenting here at PCForum, is a very slick consumer-grade site for keeping calendars up to date. It lets you manage the calendar for a little league team, for example. You can have multiple contributors to the calendar, and users can subscribe to changes, synch the online calendar with their Outlook calendar, etc. It looks like a very, very slick tool that can help families and small groups coordinate schedules. I’m looking forward to using it to share my calendar with my wife, and I’m going to tell her string quartet about it too.
Problem: Money. They want to charge for it (under $50 a year). This might work for professional organizations, but it’s a dicey prospect for consumers. Yahoo Calendar offers some (not all) of Trumba’s features, but Yahoo is free. (Another potential revenue stream: targeted ads.)
