I've been spelunking in the plugin database and I keep coming up with ALMOST what I want.
I already have a plugin that adds the excerpt field to pages.
Now what I want is a plugin that will create a widget that will randomly grab an excerpt either from a page OR a post and display it.
A plus would be something like "Random Excerpts Fader" that cycles through excerpts while the reader is viewing the home page.
I can find plugins that randomly display excerpts but they almost universally with with POST excerpts only. I haven't found one yet that works with both posts and pages.
