First you need to read Debian philosophy :) oh well is like steps becoming a monk or something
"However, before candidates are trusted with such tasks, they have to prove not only their programming skills, but also their understanding of Debian processes and philosophy. The process takes months, and there are few exceptions."
Update: it seems that debian Philosophy is hard to digest even Ian the half of Deb-Ian is waiting in "Philosophy room":
"Others worry about the time the process takes. To prove the point, Ian Murdock, the founder of Debian, whose first name forms the second half of the distribution's name, declined an offer to be accepted immediately as a Debian Developer. Instead, he began the process in May 2004. He is still waiting to advance to the Philosophy and Procedures stage"
