Second, in addition to the expansion of the genre, textual analysis has moved contrastive rhetoric to emphasize the social situation of writing.[11] Today, writing is increasingly regarded as being socially situated; each situation may entail special consideration to audience, purposes, level of perfection, and correspondingly may require varying amounts of revision, collaboration, and attention to detail.[12] The expectations and norms of discourse communities or communities of practice (cultural and disciplinary) may shape these situational expectations and practices. This is where contrastive rhetoric overlaps with social constructionism, which sees approaches to textual meaning as dynamic, socio-cognitive activities. Instead of analyzing what texts "mean", the interest is to understand how they construct meaning.
