15 years, reddit gold charter member, Secret Santa, all that stuff. And longer than 15 really, if you count the browsing I did before I made my account (I remember before subreddits were even a thing, when reddit was literally just a front page).
Still visit on desktop sometimes because unfortunately some people will probably never leave and there are communities that are useful to me that haven't migrated. Same with with Twitter, which is frustrating to no end because they spend half of their time complaining about the site but never actually fucking leave.
My mobile usage is completely gone though. I used RIF for over a decade, I'm not using anything else.

I literally just saw this pop up in my Mastodon feed a few minutes ago, funny enough. I haven't used it so I can't vouch for it, but I would imagine that's something akin to what you're looking for.
