Maybe Guides / Information could be shown on the lemmy web frontend by default to lower the entry barrier?

You can also try installing the PWA (if your browser supports it). On https://sh.itjust.works, Somewhere on the browsers web page options, there should be something along “Install” or “Add to home screen”. PWA is basically the website but without browser controls, so it feels more native.

Good to see Lemmy grow, but I hope that the decentralization will work out so that the large influx of new users will spread out as evenly as possible. General purpose instances help balancing the load, and last time I checked join-lemmy.org there have been several general purpose instances, which seems promising.
