Feedback on new 🍔 and user menus

I’m noticing on the examples from other sites around the web, that are posted on this thread, the use of:

Or a similar down arrow glyph to indicate there is a menu available under the avatar. Now that I think about it, I have noticed that some of our users never clicked on the previous notification bubble. I didn’t think to ask them, but I wonder if they never clicked because they didn’t realize it was a menu.
