On the newsletter front, I really don't keep up with them and have thought about reducing the number I have showing up every week. I mostly just mass delete a lot of the mail in my personal inbox a couple times a week.
I wouldn't mind getting back to reading more from RSS over aggregators, even though I often appreciate the comments on HN. Aside: it's a shame that so many sites removed comment sections, and any attempt to create a comment extension for any site turns into a cesspool.
