mIRC (or for you guys, any IRC client). Not as vibrent as in the old days and some missing functions in comparison to modern clients such as Discord and many more.

It is usable on mobiles, that’s what broke for me. Punch in to zoom to “home”, pinch in to upvote, different levels of text.

At home, on my laptop, I use Reddit as before on the old design, but on my cell phone? No chance. So in that area, Mastodon/Lemmy/KBin has taken over my Reddit usage, yes, completely.
