Yeah I've gotten reply notifications from ignored people. I was guessing on the latter based on what mk wrote above. (That is, I don't know that chatter and searches don't screen your ignores, but mk's post suggests they don't.) mute: The muted user cannot comment on your posts. hush: The hushed user sorts to the bottom of comment threads that you view. ...says nothing about search or chatter. Any clarification? Search especially.ignore: You do not see the ignored user's posts in your feed or the global feeds.
mk keeps fucking with chatter. Sometimes he doesn't tell anybody. He nuked global chatter by accident once. After four days I posted a #bugski about it and he said "oops, my bad." Apparently I'm the only one who uses it. Search? I would consider search to be kind of obligatory at this point. It's not the hottest engine.
We're constantly fucking with the site. It's not exclusive to content you use (although you do seem to be having a bad time lately.) For what it's worth, I use chatter a lot but rarely dive into the global chatter. Perhaps if I had more time to cruise Hubski. I feel like I'm never around anymore :(
