This paper aims at investigating some discursive features of blawgs, namely legal blogs in which legal experts disseminate and popularise their expertise. More specifically, it involves a corpus-assisted discourse study of the ways in which situational contexts affect the practices and strategies used to represent, construct and communicate legal knowledge. A comparison is drawn between two corpora representative of two different types of communication: a selection of posts written by legal experts for other experts (symmetrical communication) and posts written by legal experts for laypersons (asymmetrical communication). Combining qualitative and quantitative observations, the analysis shows that, in symmetrical communication, the emphasis is on the blogger’s subjective interpretation of legal texts and on his role as knowledge disseminator, as indicated by the predominance of epistemic modality. In asymmetrical communication, on the other hand, the prevalence of deontic modality shifts the focus on to the reader as addressee of the advice, instructions and information provided by the legal expert.
