As I said on the feature request thread, "The HTML header's title should have more page context in it so the browser's Back menu isn't a list of identical titles making selection difficult."
So if I'm viewing a comment, e.g. http://news.ycombinator.com/comments?id=13273 , the title could be "ralph's comment #13273 on Please tell us what features you'd like in news.ycombinator". Just sticking to the thread's title isn't sufficient since I'll still end up with many Back menu items the same as I traverse the "parent" links. Each different page should ideally have a distinct title.
Yes. Like now as I'm writing this reply if I wanted to bookmark this page, it would read "Y Combinator: Add Comment". From where you're reading it would read "Y Combinator Startup News". It would be more convenient for me if it was instead the original discussion/submission title. Right now, I copy the title beforehand, and paste it in when bookmarking.
I second that. I bookmark many comments threads and the default title comes up as "Y-Combinator startup news". Then I copy the post title and paste it in my title field. It would be nice if I can skip the copy-paste step.
