I found the "browse a listener" page confusing and hard to filter. One, the multi-column patchwork effect is visually messy and hard to parse. I don't know how to fix it but perhaps a single stack of page-width rectangles? Second, many of the listeners are "Unavailable" -- there should be a way to filter it to only the available ones. If a client wants to speak to a particular person, it would be helpful to know they were unavailable, but for a general browse, those entries are not helpful. (Just that many more people who don't want to talk to me, <sniff>...) Third, I couldn't see how the category filters (Addiction, etc) changed much if anything. Is it that most listeners are ready to handle all those topics? Fourth, the browse feature could benefit from a keyword search to cover those categories you haven't thought of as filters -- e.g. I'd like to know how many, if any, listeners call themselves "atheist" or "liberal".
