Well, a few folks that week in and week out tend to almost be in a race to start a thread for each and every single article on the DDI with nothing more than a post of "It's up!" and a link to WotC's paysite, well it borders on the obnoxious.
I'd be in favor of a single thread for each issue of the e-zine as was done for the print magazines or a subforum for DDI non-free articles.
As a counter-point, I'd say I vastly prefer having the ability to discuss each article and its topic independantly, rather than cramming them into a single thread. I can't imagine how you find the posting of the thread obnoxious - if it isn't a topic of interest to you, there is no need to read the thread!
But since many people clearly do want to discuss these topics, I don't think its fair to state they should go away because you prefer otherwise.
