I'm someone who, although more of a lurker, really loves Are.na. When I first came across Semble, I thought it was one of the best-designed apps on atproto but didn't think it could pull me from Are.na. I was wrong. Semble's approach to community-led knowledge sharing and information mapping is unlike anything I've seen. It somehow feels like it's tailored to the needs of researchers and academics, yet still accessible to people like me, letting me benefit from that new mental model around collecting things on the web.
