Yes and no. With comments moved into an activity feed, having my own posts in the main feed doesn't serve a huge purpose. However if this update doesn't show boosts of my notes in the main feed, I could see that being something more sorely missed.

I only want to see my own notes in a thread if someone has replied to them and I'm reviewing the thread. I don't want to see my own notes in my feed. That's what the tabs under my profile are for.
