Nothing replaces the in-person engagement. We are social animals.
The second-best tool in your marketing tool box when establishing a personal interaction with your audiences is video. When video is done effectively (great content, delivered beautifully), it draws your audiences in, and establishes their connection to your brand. While video will not replace the power of making that connection live in a conversation, it will allow you to transmit your knowledge and some of your energy; something an image or words on a page cannot do.
