>>52044966nta, she's not making these clips herself, so the only thing she's wasting is whatever chump change she's throwing at the clippers to do them for her, and not much else.
But sure, I agree in general that the idea of attracting german/austrian normies or whatever is a fools errand, and even if she really wanted to, she only goes about it in a halfhearted way anyway and just uploading some random clips every few months won't amount to any results, and she'd need to actually put some significant work into actual german outreach. Which then would really bring the "is that actually worth it / effort well spent?" question, since then it'd actually cut into the engagement she gives to her core global english audience.
btw, ever since Mori and Gura got announced as tourism ambassadors for Tokyo, I've always wondered why Kiara doesn't try to land a similar spot with whatever tourism agency Austria has. It'd probably even be an actually achievable goal, or at least more realistic than her harebrained Eurovision pipedream. I'd imagine you could convince the austrian tourism board easily to sponsor this "globally popular" austrian youtuber (given that she has over one mil subs, and there's probably only a dozen or less austrian people who also do) to make some arrangement for a campaign where she's given a few official tour videos to present the good sides of your country to the world and entice tourists to come.
And yeah, to your other point, if she just wants to get a quick sub boost to claim her 2mil present, the most promising way to go (given that we've seen it repeatedly work for smaller vtubers) is playing the algo game with trying to get some meme shorts viral. Ideally doing that with some consistency, so not just giving up after a few clips don't produce immediate results yet, and with some better content than just lazily editing a few stream moments together. Unfortunately Kiara doesn't have the greatest sense of meme culture and what material would work best, but eh it wouldn't hurt to try at least and maybe she gets lucky, or at least it's less of an ill-fated method than whatever her other ideas are.
