I send out a weekly email digest for the EA Forum.
The emails feature recent posts that have a lot of karma/discussion, 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!)
