I have a Twitter account, and I would recommend it:Now that makes way more sense. Is it worth it to make a twitter so I can stop being so behind on news, I wonder...
1) if you want to keep on top of niche news (say, vtubing)
2) you just want to see what your oshis are liking, posting and sharing, you want support them by liking their posts, or you want to see the content in their various tags
3) If you want to share stuff like memes or art for your oshi to like or repost
Also good if you want news quickly, or you prefer to curate your own sources of news, but that's a separate topic.
If you want to follow vtuber news, I would recommend you create "lists" for yourself, to get curated feeds on a subject. Takes a few minutes to set up. I set up a "list" called vtubers, and it gives me posts from various vtuber talents and vtuber-themed accounts that I follow, while I can still follow other accounts that aren't vtubers and get information on them on other "Lists".
Another useful tab is "For You" - it will just give you a grab-bag of random, popular shit based on your spheres of interest, as well as posts you might have missed made in the last day, with an emphasis on stuff posted more recently and stuff you're more likely to interact with.
Lastly, lists won't give you replies or reposts that talents have made. The general "Following" Tab will show these, but your best bet to see these is to go to the talent's twitter page for that and go to "Replies" to see all their various replies, likes and shared posts.
