(This is of course wandering down the same meta path, but...) I've always wondered if it would be possible to tag comments with tags like "tangent" or "meta" (or whatever else seems good), and then apply sorts based on that (probably in some user selectable way). > By the way, the reason we reverted the title in the first place is that the editorialized subtitle immediately provoked a bikeshed debate about the "communities" and whether they're really distinct or not—when the meat of the post is about things like fault tolerance in distributed computing. I disagree that the comment was a bikeshed debate: the article spends several paragraphs (and the first four!) talking about the relationship of the two communities, and the discussion of their relationship (both in the article and here) explained some of the ways that knowledge I knew about math intensive computing (and related technologies, such as GPUs) related to problems I hadn't previously worked on. Exploring the relationships between subdisciplines, especially closely related ones like these, is a benefit both in the article and in the related discussion.
