On advanced search (and perhaps other places) all namespaces are listed without regard to their relative prominence within the wiki. Users get frustrated when they search through a lengthy list of namespaces many of which are devoid of content.
Suggestion is to have several lists, eg "Content namespaces", "Top-10 namespaces", "Talk namespaces", "Other namespaces".
It'd be great if the namespaces listed in "Content namespaces" would match the wiki-specific configuration per $wgContentNamespaces, and the "Top-10" namespaces were ones rank ordered by their size or popularity statistics.
