It's not a community for everybody--we deliberately focus on actionable technical information and training, and tend to skip over more entrepreneurial or marketing stuff ( https://barnacl.es is a sister site that's way better for biz talk).
The culture is ongoing in refinement ( https://lobste.rs/s/oackyq/lobsters_community_standards#c_sy... ) and evolution, reinforced by periodic meta threads where aspects of the site and culture are drug up and commented on and tweaked.
It's probably the most rewarding and healthy tech community I've been involved with in the last decade. :)
