If I want to learn something technical (for example, music production) I'll search in google the thing I want to understand, then add the keyword `reddit`.
What the past few days has demonstrated to me, is how much of this information is on Reddit and how helpless I am without it, with all the main subreddits closed.
Furthermore, if I want to ask something technical I'll ask it on Reddit, and will almost always get an appropriate response. So it's been reliable for me as well.
Also, the fact that I don't need to create another account for a separate platform, just so I can ask a question about a new hobby I've just discovered. It's the fact that it's so centralised that makes it so valuable.
And as we see yet again in internet history, we see the cost of that comfortability when you put all your eggs in one centralized basket. This isn't the 90's dial-up days; I'd rather create a burner account in 5 minutes and keep my trail scattered across the net than fall into that trap where everything is in one place.
