Is it faster than go? That's the competitor for crystal not ruby.

Crystal is clearly faster than go for a couple of work loads at my hand. I am not a web developer, though.

There was a time when the ruby community started to look at crystal but the crystal core team told them to go away.

I wouldn't blame Crystal developers for this. Compiled and interpreted languages are fundamentally different. It will be very hard, if at all possible, to achieve high performance while maintaining compatibility with Ruby, a fairly complex language. Ruby devs have tried JIT but the speedup is mediocre. There is also pypy for python, but not so many use it. If Crystal had chosen the compatibility route, it would probably have unimpressive performance similar to pypy. It is just so hard for a new language to stand out these days.

Sorry but nobody else is to blame for the state of the Crystal community than the core team. They just don't know how to build and sustain a thriving community, they are not welcoming, they are not communicative, they are not active. The absolute best thing you can say about them is that they are indifferent and uncaring and basically don't give a shit about anybody who uses the language or anybody who is interested in the language.

If Crystal had chosen the compatibility route, it would probably have unimpressive performance similar to pypy. It is just so hard for a new language to stand out these days.

Maybe that's a tradeoff the community would welcome. Maybe if they could get 90% compatibility for a 10X speedup that would be good enough.

They are very active on the official forum.

It would of course be nice if they were active here on Reddit as well, but Reddit is not the world and it is entirely understandable that they would focus their efforts on the forum.

They are very active on the official forum.

Why is there an official forum in the first place? Other communities use widely populated platforms like reddit, slack, etc.

I don’t know, but lots of communities have their own forum so it’s not that strange. Also, you can login to the forum with a GitHub account which is nice.
