Hey, makers of feed readers: do any of you make use of comments-related (sub)elements in RSS feeds? For example, I notice that my WordPress post feeds, within each item element, have both a comments sub-element linking the comments area of the post, and a namespace-declared wfw:commentRss sub-element linking the RSS feed for that post’s comments. Are there any readers that make use of these in any fashion, or are they ignored? If ignored, why does WordPress bother with them? It seems like there’s some opportunity here to help engagement with blogs, either by simply linking these things inline, or in some part of the reader UI, or even by bringing a post back into the reader as “new” if comments have been added and displaying the comments themselves inline.
