I've had the same problem. I agree with your position on this issue. I beleive this subject has come up many times since the creation of that notification feature, and I suspect many others do not like it. I've taken the same steps you have, such as to limit notifications to comments, as far as email notifications are concerned. And I just took it one step further, for the notification feature at the blog, which might be useful to you too. The majority of irritating notices I get there are people "Liking" my postings. Problem is WordPress Stats and StatCounter I also use shows no visitors to my blog or a particular posting when it has been "Liked." I tuned off the "Like" buttons at my blog, and still I get "Likes" by people who have never visited my blog. I found out they are using the WordPress "Reader" at http://wordpress.com/#!/read/ where they can read and "Like" postings without being counted as a visitor at the blog. So it's like I have no visitors, but a hundred people "Liking" postings and me being pestered by that many notifications. I just figured it out, I hope. I used bulk action to delete all tags on all postings. "Reader" appears to be dependent upon tags. No tags, then my postings can't be found there in Reader. The loss of tags does not stop my blog from getting people who read postings at my blog and get counted as visitors, found via key words in title and text, still showing up in Google Search, BING, etc. That way I get real visitors who are counted and don't get pestered by notifications. I consider many of the "Likes" to be what I call "passive spamming" to get my attention, unlike "aggressive spamming" bringing the spam to me. No doubt about it, that the "Like" button is being abused in that way. And it's like Twitter users "following" me only to be "followed" back, not to read my tweets. Many WordPress users "Like" my postings only to get me to "Like" their postings or to "Follow" their blogs, without ever having actually read my blog. It appears to function as an attention getting social feature more than anything else or anything really useful to me. So, removing tags from your postings using the bulk option should reduce notifications without loss of actual visitor traffic, by stopping the social aspect of "Likes" by people who don't read anything anyway.
