This concept is nice becouse is like a wizard, and for me looks like a router for help people to find one community for get involved (QMO, SUMO, MDN …)
For routing people is important:
* Language(s): is very important know the maternal language default lang, for example i « know » spanish, french and english but my maternal language is spanish, i live in french and i use english for thechnicals issues.
* Location(s): actual and others like origin city …
* Interest: product or service like: firefox, b2g, browser id or activity like help users (SUMO), QA (QMO) … in some cases is the intersection (help firefox users)
