Is Your Agent a Listing "Specialist"?

I have seen several ads lately emphasizing that this agent or that agent is a listing "specialist". While I agree it is important for your agent to have expertience listing properties, especially in a market like we are facing, I can't help but think a listing "specialist" is missing a key ingredient. If you don't regularly have buyers in your car, on the phone, texting you, etc. can you REALLY, as an agent, have a true understanding of what is important to today's buyer? How will you know that a QR code on a property flyer is a really good thing unless you see firsthand your own buyers utilizing this tool? With all the tools we have available today to advertise our listings, I need to interact with buyers regularly so that I can see what is most relevant to them, and therefore most likely to get your home shown. Just a thought...
