I do agree with @cadawg on the mentions. Not because notification services ignore posts with many mentions, but because you should only tag people when it fits the context.
I received the notification, read the post, thought it was actually pretty good content, but because of the unnecessary mention, I was ready to leave again without taking any action.
It was only because I noticed you were new that I decided to leave this comment with the tip not to use mentions like that.
That's a much better way to put it. Thanks @simplymike
