I've reached the number of friends on Facebook where at least ONE person is having a birthday every day.

I probably only post 10-15 "happy birthday!" posts a year. So every day I check to see who's birthday it is. If it's someone I'm close to, then I post something.

If Facebook didn't have them displayed, I would probably have those 15 birthdays written down on a real world calendar, and I'd just check that.

Just a few more poorly measured statistics from me: I have 1200+ friends, have about 10-15 birthdays a week. Never post on their walls, don't have my birthday listed. Get maybe 10-15 wishes a year on my wall. Text/call about 10-15 people a year (not including family). Before I removed my birthday, I had about 700 friends and would get around 100 wall posts.

Going to try an experiment where I make a random day my birthday, delete all the posts that catch on to the fake birthday, and then change it to a month later. Will post results.

Yeah, I have seen people do this, definitely will get a lot of messages still. Facebook limits the amount of times you can change your birthday, likely because of this.
