I recommend adding something about static type checking to the list at the top of Crystal's homepage. I saw "never have to specify the type of...", and believed it was another dynamically typed language.

I actually didn't know it had static type checking until I had closed the tab, and glanced at this comment you posted here. (I know, I didn't read very far in the linked page.)

That aside, it looks neat! :)

You are right, it's far from obvious after reading that list. I updated it. Thanks!

I came across this a few months ago and ignored it for similar reasons: the homepage doesn't talk about the fact that nil is a type not a value (which is AWESOME, btw). It wasn't until a coworker encouraged me to dig into the docs that I realised Crystal is actually pretty sweet.

I recommend stating something like "No unexpected nils at runtime" and for those curious, a link for where to read more. Not having nil is basically the most important feature in most new languages I take the time to play with. Now that I know Crystal treats nil responsibly, I'm really keen to start playing with it.
