Hey! Thanks for the feedback. Mozilla is a large, public community working on open source software, and anyone can become a "Mozillian"... you don't even need to program!
This isn't meant to be sneaky. It's just people trying to help out newly-unemployed, qualified people find a new job in a tough time. And I made it public for a reason – so anyone can find out about and apply for any of the jobs!
Ah, I think I can explain. In English it's not uncommon to use a word like "nepotism" in a not-quite-literal sense. Native speakers will understand it just fine, but if you're in the position where you have to go look up the word, then it might be confusing. To get the colloquial sense of it, extend the word "family" to include friends, their relatives, and people who went to the same university but in different years.
