The mobile view seems to work very well, apart from the link to threads under Alerts, which could be larger. Often it's easy to click on the user rather than the link especially if the link is immediately below the user's name.
Aha, but people don't know that. I have had people complaining they try to click on the link, but they keep opening the member profile insted. I suppose it's a matter of learning something that on the face of it doesn't appear obvious.
