>>5424125ok, since this is bait, i'll bite it like a good membershrimp.
1) her roomate was famous on the tube long before gura's debut, she knows internet and meme culture; there is a reason she's called a meme queen around here. this was and probably still is here main social media site. Her roommate is a creature raised on /a/ and likely /b/ as well.
2) her roomate has been youtubing since she was in 9th grade. that first channel was moderately successful as well, she still has dedicated fans for it. This is a girl who knows how to make content people will watch and how youtube works.
3) her roomate's knowledge of memes and meme culture in hand Gura's launch was perfect. Not only did she amuse people with her memes, not only was her design cute, but then she sang. And man did she blow the doors off everyone's minds. It was the contrast. here was this adorible little meme girl, who can sing like a professional singer. it snagged everyone's attention.
4) she appeals to teens and likely due to the music choices in those first streams, their parents too. this is a girl who found a way to get parental approval for kids shrimping.
5) she's rather entertaining, obviously she grew up watching pewdiepie and learned how streaming games works. her roomates dabbling in it on twitch only cemented in her mind what worked and what didn't before her youtube debut.
6) the beerbug trapped everyone inside watching the internet for entertainment in 2020; gura was entertainment kids and parents could and did watch together. Her lewd sense of humor just veiled enough as to be funny to the older audiences without being lewd to the kids hearing them (much like a Disney movie)
7) she loves to sing Disney princess songs. you can't tell me this isn't knowing your audience.
8) her lewd/off color meme sense of humor is so sharp and on point it amuses older audiences immensely; preventing her from being a kids channel entirely. yes she has a young audience but she also has an adult audience. this is a line no one else in hololive has really managed to do, except for maybe korone and pekora (both of whom try to keep their content very seiso; while entertaining to all age groups, still i suspect both of their audiences are still older then guras... korone plays boomer games, and pekora is a bit... strange for kids)
9) she loves her audience, something that comes through loud and clear; this is audience interaction a lot of talents struggle to manage.
10) she's never mean. I don't know how she manages to do this, but listen to her content again. she can't even poke fun at people i suppose a lot of people poke fun at. the meanest she'll get is calling someone "stupid" and that's typically directed at a game character not someone else. Yet she manages to be playful with the membershrimp and bit back without being mean about it. Its hard to explain how nice it is to listen to someone's content who's not raging at the world or someone else all the time. I suspect this is in part why vtubers in general have taken off, but still it's a big reason why she's fun to watch
11) I suspect she has a sign hanging up where she can see it, that reads something like "always leave them smiling", gura seems to make it her goal to make her chat HAPPY, and to leave them feeling HAPPY. no matter what might be going on, how nervous she feels how ill she might be, she does her best to make the audience feel happy, and that is something I think reaches through the internet to everyone who watches her.
