Most people start by ending up on the join Lemmy website and are bombarded with info about the fediverse, and the description of each server makes it sound like you can only interact with local commities. If you link someone straight to lemmy.world I imagine they will have no problem signing up.

I would recommend giving wefwef a try, it’s been less buggy than Jerboa so far.

It’s shocking how much faster Linux runs compared to a modern windows installation. I do worry however that as more and more programmers focus on web apps that we will eventually see the same problem on Linux as well. Developing desktop applications for Linux is already a pain and the ease of making modern web apps will amplify the problem. At least Linux won’t have all of the awful bloat that Microsoft runs in the background on windows these days, but I don’t think we will be able to escape from web app hell on Linux.
