After using your website a bit, and checking out the page source, I've got a few suggestions. Most of these have probably been considered already, but humility was never my strong side :) Without further ado:
Feeds for news and search results (person / company / non-profit) would be useful for anyone interested in the project or data. Could be set up as DB triggers to avoid getting the data again for every user.
Broken / disabled links should be hidden, not greyed out. That way, you remove ambiguity.
