Subreddit Rules
  1. Don't set r/fsharp on fire: r/fsharp is small enough that long argument threads can completely swamp the subreddit.
  2. No Personal Attacks, If you have a beef with someone, hash it out somewhere else.
  3. No Flame-Baiting, which includes disparaging entire groups of people (Ex: C# developers) or approaches within the F# community, in such an odious way that starts a long argument thread.
  4. No Dog-Piling, If someone said something odious and off topic, just report it, don't try and shout them into submission.
  5. No low-quality content: Content must maintain a semblance of quality and effort on this subreddit.
  6. Low-quality content includes: * Asking basic questions that are easily answered with a search engine, in a way that brings nothing new to the table (ex: "What's the difference between List and Array?") * Fortune telling without sources (ex: "Microsoft will give F# typeclasses.") * Vague/unconstructive negative posting (ex: "MSFT never contributes/MSFT contributes too much/People whine too much")
  7. Content must be on-topic: The topic of this community is the programming language F#, and as such, all submissions must be have something to do with F#. We're fairly liberal with what that means: this may potentially stretch to functional programming or .NET topics, provided it reasonably applies to F#.
  8. On-topic examples:
  9. New F# book is out! * .NET 9 released * How monads work
  10. Off-topic examples: * How Git Works * Beginner's guide to C# * Check out this new Javascript library
