There are some legit things to want to know about realtors. How many homes did they pressure people into whom then had various issues they needed to deal with? Or, did the realtor truly find a good fit for the buyer? How about conflicts of interest? As an anecdote, my neighbors recently were screwed by a realtor that pressured them into a place where they then needed to drop 150k on repairs (about 15% total value). That same realtor was pressuring our HOA president to literally make up information for the resale information so that the forms could be handed back to the realtor just a couple days sooner. Of course all liability would have been on the HOA president and not the realtor. With that said, a good history of what the realtor has sold before, & how the homebuyers felt about it would be a great tool..
