There are different activitys which are posted on your own wall automaticaly (e.g. user received chocolate frog card xyz). These posts sometimes feel a little bit like spamming your friends with somehow useless information.
To reduce this "spam-feeling" my idea is to make it possible for a user to select activities that should be posted on his/her own wall by the user him/herself.
Either by (1) a general setting where the user can generally choose what will be autoativally postet and which activity is "secret" or by (2) a post by post setting where the user can pick if an automatical post will be generated on the wall or not.
