My feed on Instagram is filled with Nature / Science Documentaries, Comic and Cartoons Reels (Pokemon, Tom and Jerry, etc). But sometimes comments will exhibit the usual shenanigans (i.e. “I don’t believe in evolution”), or accounts that used to be legit suddenly devolve into advertisement spam.
I make sure my preferences are kept by liking the content / posts that cater to them so the algorithm shows me more of them. Of course, I also set a timer on Android so that I don’t spend too much time on the platform (20 mins a day)
Local SG here, as far as I know direct underground connections between buildings are only common within the city area - head to the heartlands / fringes and you’ll see some sunlight
I tried Google Maps Live View (i.e. AR View) to navigate underground, but it’s a hit or miss.
