This is the way

Crystalizers?

Hmm, perhaps Wyld Crystallyns?

I too wanted to make this pun, glad I’m not alone :)

There are lots of alternatives. There was a large thread on the forum discussing it and there is basically no consensus for a preferred term.

As someone from the US state of Michigan that has at least two competing demonyms, I actually find the idea of everyone using a different form based on preference to be charming.

Cooks? :-)

Easy there Jesse

Geodes?

I think this is an underrated response given that any crystal can start as a geode.

Geodudes?

Crystian? ;)

With Crystmas as official language day? I'm in!:)

Sounds appropriate given that Ruby already does all its major releases on Christmas day, considering Crystal's close relationship with Ruby.

Shardies

Crysties!

Strahler / Fossickers?

Crynge.

Pfff, yesterday i talked with a Brain fucker...it was terrifying. Can we just stop calling peoples after tools?

Generally I would agree, but in this case, "Crystal user" isn't that much better.

A developer who uses crystal? Like a builder who uses a hammer is not a hammer-user ;)

EDIT: Wow that took a long time to realize what you meant...haha no, truly not good, and thinking about it my comment "A developer who uses crystal?" is now terrible too.

Crystal dev

Problem solved

Develops the best Crystal on the market ;)

A "tool" is probably the best term for someone who actually uses BF.

you people must be fun at parties :)

I opt for meth heads
