Same here I started a youtube channel 1 year ago and as a fan, I made a lot of video about BG3.
It's a very small channel, I'm learning how it works but it's clear that players are really hyped about the game. As soon as there are new informations to share I have a lot of view/new subscriber but 3 monthes without any interresting informations is way too much to keep the hype really high.
With a roadmap and even small communication every 2/4 weeks (data, employees interview or anything else), I guess big/good BG3 youtuber/streamer like Wolfheart could keep the hype at 150% during the whole EA without it ever going down.
But hey... After you streamed your grandmother playing the game... What else can you do if devs aren't giving you something ?
