Shameless plug for the thing I built: https://news.ycombinator.com/item?id=46672734 - meepr, basically not algo driven (except the hashtags are curated), no recommendations etc, if you wanna "grow" on it, you need to tell your friends like the good old days. It's just run by me, not planning on having it run by anyone else, if people like it I'll add a subscription to cover the server cost. (check out the retro theme!! :))
