I think it would make sense to add a button to edit what shows up on your own usercard while viewing your own usercard. It’s not at all intuitive to find out how to change that info, and it requires several clicks. Here’s a mockup of what I’m suggesting:
Without it, the most obvious thing to do is to click your name, which takes you to your “activity” page, which still requires two more clicks (the first one not at all obvious) to get to where you can edit the info. So I’m also suggesting adding a button on the user header like so:
This seems like it would be having the right options in the “right place.” When do people get the inspiration to update their profile? When they’re looking at it. Let’s make it easy.
