Nice! I read in a wiki that the fn+space key combo didn’t work on the T14, but perhaps that’s outdated info now.

To me, a downvote means “what you wrote contributes nothing to the discussion, and should be less visible”. If someone downvotes me, I take it as a sign that no further discussion in that direction is meaningful.

Does the keyboard backlight work out of the box? I heard you had to fiddle a bit to get that working on newer thinkpads.

You got your answer, I guess.

I think the idea is that what we want to see more of is genuine discussions in good faith using sound arguments, even if we don’t personally agree with the viewpoint.
If I’m just tired of seeing certain types of posts I can block them without downvoting their posts.

Isn’t this the dilemma? Each type of fediverse project has its own focus, presenting posts in different ways. If we increase interoperability to the point where everything can be presented fully on any service, will each service be able to keep their focus? Would there be a point in having pixelfed when mastodon exists?
