I wonder how much this translates to places outside the US... Bluesky being the place for everything Center-left and left of it by US standards would just make it the place for mainstream opinion in much of the EU.

Personally I found it much easier to avoid politics on Bluesky than on other platforms. Which is why it's been more sticky for me than Twitter was. And I put that down to having good feed control, and not being beholden to an algorithm that tries to keep me engaged.
