Crystal is a niche within a niche. Only somebody interested in ruby will care, and then only somebody interested in ruby who is also interested in the use cases where crystal is superior to ruby will care. By now you're in a pretty small subset of the overall programming community. This is bad enough. Worse, the use cases that crystal aims to solve for ruby, are not things that would attract people to ruby in the first place. Few people need a compiled language and reach for ruby, to find it lacking, and then look at crystal. The people with problems that crystal solves were never looking at ruby in the first place. They're not interested in tricks like `1.day`.
