My favorite part is the tongue in cheek title for Tim Berner-Lee: "Web Developer". That's an understatement (as well as a perfectly accurate one).
No seriously, TimBL should need no further title, given their audience ;)
That would be my guess anyways.
On top of programming, I also do system ops, ui design, customer service (and client service), project management. Developing a web site takes a lot more than programming, especially if the team is small.
