One party, elected by itself.
It's a coalition, as, indeed, the SED was; the unifying element is that
an alternative to consensus is necessary to achieve their goals. Goals
include excellence, universal acceptability of content, better public
relations, and control over content. Centralization of power is a
subtext, a necessary evil.
The alternative is to made responsible community decisions, for example,
nominations and discussions of what should be picture of the day, rather
than simply letting anyone put any featured picture up.
