Aren't there free previews anymore?
Admittedly, this might be a bit hypothetical, but there simply is no way to tell from the title or the post or the link, that it is not useful for anyone who has no
DDI subscription. There is a hint ("dragon magazine"), but that's it.
I can see it as being a bit annoying to follow a link like that, hoping for some information and only finding that you have to pay for that information.
Something more telling ("
DDI subscribers") would probably prevent that (whether that is necessary is another question; I just think it is worthy of being commented on).
And as I said half in jest, the first post is actually very close to advertisement spam (it's basically on topic advertisement spam

).
Bye
