I just saw that the Newest Nodes page now shows the name of the poster. Very nice!
Here's another idea I had just now: next to each link in Newest Nodes, add a link to the top node of the thread (where it makes sense, e.g. for "Notes/Replies" and "Categorized Answers"). Sometimes I want to see the latest replies, but I also want to see the whole thread for context.
Thanks vroom for your great work in this site. It is certainly where I spend most of my online time lately :-)
