User blog comment:Jenburton/An Update on Message Wall/@comment-3388044-20111001062627/@comment-1091639-20111001182259

Xd1358: I agree. Article comments themselves are insufficient if the contributors want to discuss updating the article as opposed to discussing its subject. But for now, we're only discussing user talk pages, aren't we? My opinion might be biased by the fact that I mostly contribute to small wikis but on those wikis I rarely see more than 3-4 editors discussing something on a user talk page. From this perspective the Message Wall is an improvement.

I can see how Article Comments can be troublesome on more active, bigger wikis, but if the new communication feature, which would replace Article Comments, is updated and adjusted to facilitate more active discussions, similarly to the previously linked translatewiki.net Liquid Threads extension, then the problems you mentioned are solved.
