Please restore email digests

I think it is more advantageous to keep improving summary digests as those are sent out everywhere and benefit everyone versus the teeny tiny minority of people who want this other obscure feature.

Maybe we should start with making sure this is true?

@sam

you can set it to email daily, unconditionally (as long as content exists)

I’m pretty sure this isn’t true yet:

Both having been seen recently and having been emailed recently can suppress a digest. I suggest fixing both:

• Receiving a normal notification should not block the digest from being sent. This would require introducing an additional column that stores when the last digest was sent.
• There should be a way for a user to ask for digests even if they have been online. This could either use the site setting Send me email notifications even when I am active on the site or be a new one.
