More to the point, ruby always uses string with more than 23 character. It's strings that are passed to the client and an HTML page is almost always bigger than 23 characters.
Ruby is a general purpose scripting language that can be used for web development (rails, sinatra) but is often used for different purposes (puppet, chef, vagrant, shoes, ...).
And even if you'd assume web development as the only purpose, there's a lot of strings that are shorter than 23 characters: Header for request and responses, form fields passed by the client (usernames, passwords, ...), field names passed in hashes, table and column names, template and file names, URLs or even the occasional, totally rare string in a json structure. It's an optimization with major gain and little loss.
Actually, my comment needs to be understood as an answer to the OP's title "Never create Ruby strings longer than 23 characters".
I understand that there's many places where strings are shorter than 23 characters and I never meant to say that this optimization was superfluous. I actually think it's pretty clever.
