I only see the "last seen" info when hovering over my own name, not others.
Same here. Not sure if the changes to being able to see online users and what they're looking at was intentional or not, but it's a feature I miss. I used to spend a good amount of my daily TMF time checking out what like-minded people were checking out or revisiting and it usually led me to great new content that I might have skipped over or old content that I didn't check out when originally posted. I'm hoping some of the features that facilitated this will be brought back...
