If I'm signed in it would be nice if there was a link to "my activity" right from the home page. Or at least as one of the options under my avatar. Also seems redundant to have a 2 links to your profile when you click on your avatar. Maybe just add one for "my activity" and get rid of the link within your name as "profile" seems pretty straight forward. Just a lot of clicking to get to my activity.
On another note. I'd rather the default be to not notify me when somemone replies.
