I have an annual subscription, which runs out in February, for which I have disabled automatic resubscription as of the date the online builder was announced.
This is precisely my situation. (Expiration month and all.)
I've answered the poll with the "used to, but have stopped" option.
The sort of players/DM's that invest time checking out messagesboards about D&D are the sorts that will generally invest money in the game, like on a subscription.
I imagine about half of every gaming group don't invest as much time or money in D&D but still regularly turn up for games, so won't have a subscription, and won't respond to this poll.
It does interest me the number of people that are ex-subscribers though. I didn't expect it to be so high.
