I don't think overall it has really caught on like VRBO...which has been around for some time.....as to your question, i believe it has increased some rental bookings and drawn a bit of traffic! I think in the long run HA will phase out VRBO or make them all one. the website for HA is more user friendly and the search feature is much better. if they keep raising the price on VRBO pushing people to HA, i bet people will jump. also, i think it's regional...people here use VRBO vs....say Texas where HA is located or NY. I push VRBO but add that HA will increase your chances. it's all better than putting 25% into someone elses coffer! at least your working on a forum that gains momentum everyday it would seem!
