I chalk it up to cultural differences personally. It's not inherently good or bad; one advantage of having many smaller threads is they can be focused on specific things. For example, instead of having a BLM megathread where you have to dig through it to find conversations you care about you can find threads talking about specific BLM stuff, like ice paradox, thunder procs and so forth.

In that sense I prefer the style of having many smaller threads as it's easier to find posts that are focused on talking about what I specifically care about
