Seeing polls are quite popular recently, I would like to create one too:

At the moment when a user engages in a thread (say by commenting or following it), they are included in the notification list until they un-follow. As per very old logic, they are notified about all the comments, inc. any replies to any comments - as one can expect this might be too much.

Just to be 100% clear - the answers relate only to the case when user is following the thread.
