How many hats does a Webmaster / Webmistress wear?

I thought it would be fun to write a "job description" for an open source, one man band webmaster (me at that time).

Of course, the number of staff doesn't really matter - a job role is a job role regardless of who fills it - but of course there are considerations with the management of people (in whom one has varying degrees of trust).

So, how many hats does a one-person-webmaster need to wear and what skills does she/he require to competently wear those hats?

By the way - I'm talking about a webmaster who designs pages for humans - small businesses or hobbyists who simply want to sell their wares, promote themselves, or get a point across - not one who specialises in cloaking and a million cross promotions and sales - this does not interest me (I get dizzy looking at "Piccadilly Circus" sites).
