I send out a weekly email digest for the EA Forum.
The emails feature recent posts that have a lot of karma/discussion or seemed really good to me, as well as question posts that could use more answers.
What people are saying
"Awesome, saves so much time. Thank you!"
"I really like receiving these! It's very helpful, and I often get ideas for sharing things with the rest of [the research org I work for]."
"Thanks for putting this together - very valuable to have a curated selection."
"It doesn't really feel like there's enough stuff on each newsletter - I think having it be monthly rather than weekly would work better." (Not all feedback is positive!)
