One feature I do like in Facebook that Google+ did not have, until yesterday, was the ability to be reminded when your friends and family have birthdays that day.
Irene Chung from Google announced on Google+ that Google now has that feature.
Assuming your circles on Google+ share their birthday with you, you will see a notification of your friends (circles) birthday for the day and you can wish them a birthday greeting. Same with you, if you share your birthday with your circles, they can wish you a happy birthday greeting.
Irene from Google explained:
Everyone deserves a little love on their birthday, so we’re making it easier for you and your friends to celebrate on Google. Starting today, you’ll see a reminder on Google.com when someone in your circles has a birthday! From there it’s easy to share a fun message, photo, or video with the birthday gal or guy.
When it’s your special day, we only remind the people you’ve chosen to share your birthday with. Update your Google+ birthday preferences to make sure you’re sharing with the right people: https://plus.google.com/up/birthday
At first you’ll only see birthday reminders if you’re searching in English on Google.com. We’ll be rolling this feature out gradually over the next few days. Here’s to all the happy birthdays to come!
