I think that's time to growth to the next wordpress CMS generation.
Nowaday all are perfect in wp, we can do amazing thing with it :
Blogs, Portfolios, CMS, E-zine, Government websites, Social utility...and more.
And the must thing we (as many users ask for) need in WP, it's an Advanced search form (mini exemple http://wordpress.org/search/) which we can to config easly, to let users search in our category, Custom Fields, or pages... (already in Dropal).
Imagin that with Advanced Search form of WP we creat our Reallestat theme, people can search over price or room... or a Government website, that we can cheek for a documents, news... or in my perso page, which my fans can search for plugin, news, images... why not in a social utility to search a friend in a city, country, sex or age...
I think that the WordPress need to fight and growth up over all other CMS like DROPAL, in JUST the develop a strong ADVANCED SEARCH.
Hop WP team hear me as to hear to all WP Community over the world.
