For some reason companies like Facebook, Apple, Google, think that our entire lives revolve around birthdays.
Facebook is obsessively pushing birthdays to the top of every day’s priorities. Skype has special notifications to inform us about our contacts’ birthdays. Google computes dynamically a calendar of our contacts’ birthdays and merges it with our calendars. Every time I set up a new mac, it takes me weeks to get rid of all the birthday notifications and calendars automatically retrieved here and there.
All of this is annoying.
