If you visit your profile there is a bar beneath anything you may have put in your bio that lists options for overview / threads / comments etc. Subscriptions are included in this and if you click it will display what you've subscribed to. Mine is greyed out since I do not have that set to public view, but if I click on it myself they will still display for me. They seem to be in order of when you subbed right now. It would be nice if there was a way to show it alphabetized, but perhaps a different way to view your subs is coming, as this seems a bit of a workaround solution to what you're looking for. It's how I've found to do it.
