I loved that I could build a career ladder by leveraging like organizations that had public profiles. I also loved that my teams could track their wins against those ladders and have it all visible for managers and ICs during performance reviews.

I know that the technical team is using it and it's been very successful

You could easily identify what you need to improve to grow, discuss them with your manager, and take action to gain better knowledge. It is easy to use, in most cases.
