Newcomers interested in this page will have a hard time finding how who to ask a first question. Can we have a list of contacts here, even in the form of a nice gallery of people? It is a lot more welcoming when you find something like this.
There is a link to Wikimedia Product Development, a stub that links to Staff and contractors at the WMF site. There are links to tech-ambassadors (not the right place for this), the list of maintainers and the list of projects (both implying that you have already a good idea of what are you after).
