Why are some love notifications grouped together?

To keep your notifications clean and easy to follow, we group loves together:

• When one member loves several of your pictures, videos, writings, status updates, comments, or other posts of the same kind, you get one notification, for example "loved 5 of your pictures".
• When several members love the same post, they're shown together in one notification with the total number of loves.

You still see every love. They're just grouped so a burst of loves doesn't flood your notifications.
