I work at AWS. My thoughts here are my own and do not necessarily represent AWS.
Possible to somehow highlight the new posts since my last visit and add a number next to the left-nav items to show how many new posts there are?
I believe this already happens.  Or maybe it's new?
I don't see any numbering like what's shown in your screenshot, but it could be because of the still relatively low volume.
