Regarding personnel changes in Fedora

["Jóhann B. Guðmundsson"]

Given the recent announcement regarding the new Fedora program manager 
and since I got asked I just forward those question to the right people 
who can clarify these things for people preferable on a wiki page(s) in 
foreseeable future.

Who are Fedora personal?

What are there responsibility and roles within the project?

Where those roles created by the community or Red Hat?

Are those roles filled with Red Hat employees who get paid to serve them 
or are they being filled with community members?

Thanks.
