So, we may not be able to turn it into a single discussion - the news items themselves are simply a separate beast.
We can still take non-edition-specific threads in the rest of the forums, merge them, and move them to General when they come up. You may still have some separate discussion associated with the news item, but would I be correct to guess that the volume there is much lower than that seen in the related forum threads?
It is; but it would benefit EN World immensely if that wasn't the case (for various complicated reasons, but it's in the site's interest to have well populated news threads).
Which is one of the reasons I agree with Whizbang - we benefit more from good solid threads than we do from several fragmented threads; and we benefit more from that being on the news page than from it being buried in a forum.
