Two small points that are almost bug reports. I’m a long-time reader but very occasional contributor, so I haven’t really involved myself in all the impressive new social network-style features.
Firstly, when I’m reading an article, want to comment, and sign in, it takes me back to the site front-page. Could it not redirect me to the page I was on when I clicked the sign-in link? (The site exhibits the same behaviour when logging out, but that’s less of a problem in most instances).
Secondly, when I tried to report the above on this thread using my Android phone (HTC Desire default browser), the “View non-mobile site” link just ended up reloading the same mobile site view.
