You can stay close to your customers by using video marketing. You could ask the people watching your videos to send you ideas or questions that you can make short web shows about every week. If possible, offer a prize or incentive to customers whose questions were used in the clip.
Use other people such as guest speakers on your site and in your videos. As interesting as you might be, your viewers will really appreciate seeing a fresh new face. Make sure that whoever you have in your videos reflects the kind of message you want to send to your viewers.
