In another post here (Anything we can do to bring dormant high-rep users back?), we discussed how to bring inactive users back to participating at QSE. Having been less active recently myself, I realized how much I'd appreciate once-a-quarter email with:
3 best rated questions
3 best rated answers
3 unanswered questions in my highest-rated tags (i.e. if there are 3 unanswered in my highest-rated tag, then I'd want those three, otherwise then move gradually down via my highest-rated tags).
It would be great if the user could opt in for such digest-email via their profile settings.
What does the community think about such proposal? If this gets enough upvotes, could we then try to have that implemented?
