One thing I have come to not is that when it comes to posting content, @dbuzz acts as the best gateway: https://leofinance.io/post/@vimukthi/d-buzz-the-gateway-social-media-dapp

What you are doing can seriously help the growth of the platform. We have to break the bubble we have created within HIVE. @cflclosers was pushing YouTube a lot as a place to promote HIVE. It is a very smart thing to do. If we target other alternative social media websites, the targeting can be even better.
