Let me try. The F# (nonexistent) community isn’t actively unfriendly, but passively. This forum is the F# community. This fact seems to have been missed by (all?) “community” leaders as, for example, important announcements are made elsewhere, discussions are done in a different client altogether, experienced people prefer to push their own content (there are blogs after all) instead of engaging actively here. It’s just all over the place, minor bits and pieces here and there. Even the people running for positions on the F# Foundation just posted a single message, looking like they ticked off a work item rather than engaging with the community.
90% of community members are lurkers. Look at said forums, Elm being a great example. It uses exactly the same technology as this one and is vibrant, with lots of announcements and active participation from the founder itself. Lurking there for a while gives you a good sense of what goes on. In contrast, this place is derelict and feels abandoned. Perhaps this is the true state of F# today?
