Dan Grover’s UVCalendar.org is an events aggregator for the Upper Valley. Dan has plug-ins for several of the Valley’s online calendars and it’s out in Beta as of this past Monday. My wife has already been using it for a week or so to plan her and Emma’s days.
There’s the outstanding issue of how one intelligently combines freetext events from multiple sources (with different wording and free-forms) but that’s a hard problem in AI research so we’ll just have to filter our own dupes for now. Still, an excellent resource for Upper Valley citizens. Check it out.
