Such an Inbox collection should also have information about who dropped a programme in there, and a comment/message.

UI-wise, sending a programme to another member should be integrated with other sharing options (such as send by email).

As a workaround, since the feeds I subscribe to is a (significant) subset of the feeds I have rated, a list of feeds that I have rated would be a good starting point.

This would make it easier for me to find the programmes I have just listened to on my iPod in order to rate them. If I could mark all the feeds I subscribe to, they would show up on my profile page. Now only my queue (and other collections) are there, the rest I have to find using the search pages. (Most of the stuff I listen to is not from the queue, but from feeds that iTunes is directly subscribed to)
