Random interesting stuff from q&a's at #HDLS15: subjects aren't produced a lot in discourse (at least in home sign systems) and neither are anaphors (in Ticuna (Amazon)).
Additional examples that the stuff linguists may examine/foreground, though useful (!), don't necessarily align with what language users are actually using
Because connections to stuff I've written about: Laura Downing at #HDLS15 mentions biases in documentation e.g. salience of linguistic forms to outsider fieldworkers can determine what gets documented and documenting contrastive forms is less controversial than non-contrastive ones.
Also her work on laryngeal stop inventories in #African #languages relied on documentation of non-contrastive forms.
