I don't see any difference - I still get an email for every post on the thread. Or at least I guess I do - I certainly don't get emails only when someone replies directly to my post. The inbox still fills up albeit perhaps a little slower.
I used the emails to know when someone replied to me, but that just isn't possible now with the volume of emails. The only way I can know is to individually check each post I've made lately.
Thanks for the feedback. While the changes were generally successful, there were a few bugs where people were still getting more email than they'd like: I think that we managed to track these issues down and hope that they will go out with our next site update.
Also, this next update will have a change that many users have requested: we will notify you of all direct replies to your posts, and only email you occassionally if there are other posts that we think will be of interest to you.
"we will notify you of all direct replies to your posts, and only email you occassionally if there are other posts that we think will be of interest to you." Yea that would help. I canceled all my hubpages email because I can't figure out how to get into my hubpages email settings i.e. the security questions, which I don't know the answers at all.
