IG birthday - wall notification

Now that the update of realistic aging has been implemented on the site a while back, IG birthdays seem to pass almost without notice. Perhaps it would be a small but fun addition to add an automatic wall notification on someone's IG birthday saying, for example, 'Lucy Kingsford has turned 23 today!' or 'Lucy Kingsford has her birthday today'. This way, you don't forget it yourself either and it would just be something small and nice that I'd like to see! It could be as simple as the little example I made below.
