@dob from Livepeer here. I don't think that was @dan in the forum. We haven't met before, but we've certainly been inspired by Dan's DPOS design and implementation, and have a lot to learn from Steem and Graphene as we bring Livepeer into existence. I don't see it as a Steem competitor since it isn't a social media site. As a live video infrastructure platform, people can build all sorts of video services and applications on top, but the plan isn't to make a social site where people vote up and down on live streams.
