This should be the top comment, especially since organic search has been lost. Not to be overly critical because Codepen was great in its time, but it's now on individual websites to upgrade their search game if they want to stay relevant and useful.

Edit: Just noticed that logging in is now required for search. I'm sure this is an attempt to prevent AI scraping, etc., but it's a big mistake IMHO. While I have an account, I don't log in much and tend to abandon sites that require log in. Among nerds, I'm probably not the only one like this.
