And in the mean time?

Also "can" doesn't mean "will". And most, myself included, aren't going to be willing to just...hang around...for months or years or however long that takes to happen. And every time that happens, the timeline gets pushed to the right.

In my experience so far here, there's significantly better odds of running into trolls on Lemmy than Reddit.
