I've kind of gotten into PWA's phone wide. I went through my app list and replaced as many as I could. I had to go back to one or two apps when the webpage didn't cut it, but it's working pretty well. As a side effect, I had also cut down on my Google search usage about a month ago and I have noticed that ads (within Facebook at least) have gotten a lot more generic. So apparently the walled garden that hermit created is working.
Normal Lemmy site can be used as a PWA and you can just login and do what you want. Also Jerboa works fine for reading and marking. So could use that to read and mark, and then do replies with PWA. That is what I do.
That's not feasible if you upvote a lot of stuff. There's a difference between, "let me upvote this so it gets visibility and to help there be activity on this site so it can grow" and "This has a piece of information that I want to look at later when I need it."
Yes, I just use the normal Lemmy site presented as a PWA or just my workstation to post and comment. Use Jerboa for browsing and marking. Works fine for that, but seems to be less then reliable for commenting.
