@Mike Schinkel -

Millan in particular has contributed strongly to WordPress. Users, other developers and Team-WP all benefit.

Developers differ/vary a lot. They are both 'coming from' and 'aiming for' different places. They would not/do not agree on the merits & ranking of functionalities "important to developers".

And how could it be otherwise? Users - whom develpers server - are themselves 'totally all over the map', representing a huge range & diversity of motivations & objectives. Different developer-shops try to build businesses with different parts of a spectrum of sometimes sharply contrasting user communities & needs.

The WordPress Team has a very complex scene to take in, and balance. I myself - gasp! - do not agree with every call they make.
