Laurent Brugiere it was changed at some point due to probably some "complains" where We end-users received a lot of notifications for each post/comment update here. Currently we will get email notification when Admin submit a post and when someone will be mentioned. This will change once the user will see the Notification Manager I guess.

Currently there are 2000 users here and if all of them will get all notifications from post it might be stresful for majority of users but from the other side it was good so everybody were visiting this Commnunity. Lets wait...
