Nice to Steem you @louisthomas, and thanks for covering this topic! (I'm gonna follow you, from now on). What I'm wondering is if we should really be pushing for "very popular" personalities to join our community (and the DTube one),... or if we'd better go on attracting "highly qualified" people?
For instance: I know I'd be more enthusiastic by hearing that a maverick historian, talented in recording and telling important past events and processes, is beginning to post her or his videos on DTube, improving global DTube quality, than learning a 100 million fans youtuber is adding his footage on DTube, if he's only surfing on some hype content we'll all have forgotten 10 years from now...
I guess the same comparison applies to the different blockchains and the pace of their building process.
