I hadn't really actively engaged with Reddit in years, and I stopped lurking almost cold turkey when they killed off the personal homepage on the mobile web interface earlier this year. I deleted my account when the Apollo news broke (I've never even used a third-party app, but it's crystal-clear what direction the wind is blowing). I only found out about lemmy after I pulled the plug.
Now to figure out how mastodon and all the other "fediverse" apps work :-)
