In the past I have enjoyed the feature of being notified when a post I have commented on receives a new comment.
However, as the practice of "+1s" (I'm guilty of this as well) and "Your vote has been recorded" has grown, the notifications seem less useful to me.
A few ideas:
1) Discourage the practice... encourage the use of the "Like" button. This has the added benefit of keeping a tally in the list of posts to show relative support for topics. Perhaps there is an additional even more obvious way of indicating this type of "Like" and therefore encouraging its use.
2) Enscape team could avoid replying "Recorded the vote" this would both discourage the practice and possibly avoid another irrelevant notification (possibly bc not sure if it triggers a notification)
3) Can a User disable the default notification behavior for posts in the Subforum "Ideas and Requests"?
