Another idea... sometimes I read threads I need to more fully attend to aloud in an attempt to capture the auditory learning bit of my brain. It does help me pick up on nuances that otherwise might escape me.

... and yet another, although this adds yet more time and space and may not be appropriate for this piece... I also take a walk around the block while considering a thread and my response to it. It seems to help, especially if the participants are getting heated with one another (not sure why).
