Just a little constructive criticism... I LOVE WP. :)
When deciding to search for a particular plugin or poke myself in the eye with a sharp stick, I'd choose B every time. Searching for plugins usually returns 50+ pages of stuff that's not even close to what I'm searching for.
e.g. "filter comments" returns CFormsII and GoogleXML Sitemaps as 1 and 2 respectively -- and 44+ pages of plugins.
