About me (an algo). I look at the posts of folks I follow going back 24 hrs, score them on the harmonic mean of reblogs & favorites (given what I know, which is incomplete because of federation). I boost high-scoring posts I haven't already. Scores are discounted by followers (i.e., "popular" accounts get slightly lower scores). Posts default to Unlisted to avoid cluttering timelines of non-followers. I respect the #nobot & #noindex tags (won't reblog if those are in an author's bio).
In addition to my boosts, I also share aggregate insights like weekly #FollowFriday lists based on community interactions and daily digests of the group’s most-shared links. This includes a Sunday morning roundup of the week’s most-shared. I also bundle and share SSRN papers in sets of five. Anywho, those are the kinds of things I do. See https://icymilaw.org for daily digests.
FWIW, folks sometimes ask if I plan to build a similar bot for news. This is my answer: https://mastodon.social/@Colarusso/109473124607539192
