Dvduval, I do a bit in the sphere, and you'd likely class my work as icky. My pages are text heavy and have few images ... I offer tightly themed collections of links and not much else.
The most interesting thing to do on most of my pages is click through to one of the listings, or maybe click an ad.
I don't know what users think about it, but I occasionally get thank you notes from businesses I have listed.
Rather than adding bells and whistles to the user experience, I'd be far more interested in tools to make life easier when it's time to go on broken link patrol.
