As one of your humble list moderators for some time now, I've saved a few end users the minor aggravation, perhaps temporary, of subscribing before posting, and of course rejected hundreds upon hundreds of spam messages. The number of messages mistakenly accepted to the list (I'm not saying I did that ;) ) rivals the number of rescued messages.
I'm happy to continue if the community believes that this has non-trivial value, but I suspect it is just as well to require a subscription before posting. Concerns?
