Don Park on 'blog calendars

Enriching Blog Calendar.

Most blogs have a calendar for navigation but not for much else.  I was thinking how nice it would be to enrich it automatically with other information like birthdays of people on blogroll, anniversaries, schedule of conferences I am planning to attend, etc.

Size of the calendar will have to get a little bigger, but mouse-over sensitive date specific details can be displayed in an area immediately below the calendar.  FOAF and iCal/vCal formats can be useful here.  Calendars are also amazing yet under-utilized advertising medium IMHO.

[Don Park's Daily Habit]

Don writes about something I hadn't even thought about:  my calendar.  I don't use it and don't see why others would.  I read weblogs for two reasons:  topical content and continuing stories.  I'd be more interested in a good category list rather than a calendar.  I'm considering removing mine.  Can anyone out there educate me about the calendar's benefits?
