I'm starting a newsletter about Japan and I'm not sure whether it should have an online archive of past issues. If yes, only available to subscribers, or widely publicized all over the net?
I think this is a difficult question. Of course, such an archive would create a valuable knowledge base, make available past issues to new subscribers, and promote the newsletter itself. But on the other hand, there is the risk of it becoming just a "secondary blog," loosing the newsletter exclusivity aspect and lowering the value in subscribing to it in the first place, instead of using RSS or visiting the archive website directly.
What's you opinion?
