Well to be honest, right now isn't the time to focus on communication, PR nor hype. The userbase here is somewhat miniscule, so not worth the effort imo. Once you pass the testnet phase, then it's time to start using resources in that apartment too, since marketing is essential, no matter the product.

I've seen high ranking posts on Reddit regularly complaining about Youtube, I'd build a bot to notify of those and always inform users of DTube there. That kind of guerilla marketing is the low hanging fruit to start with.
