One option that’s smaller than link posts might be to mention in the AF/LW version of the newsletter which entries are new to AIAF/LW as far as you know; or make comment threads in the newsletter for those entries. I don’t know how useful these would be either, but it’d be one way to create common knowledge ‘this is currently the one and only place to discuss these things on LW/AIAF’.
