I'm logged out by default and only log in to comment, which is rare. I don't like leaving my username up for display if a friend/family member has to borrow my laptop for something. I've engaged in a couple of communities that are a little more counter-cultural than my peers.

You can create another account, or another 10, reddit doesn't mind.

Done this. Eventually one account always becomes my main account and I'm back to square one. I don't care enough about reddit to keep up with 2 separate accounts.

There’s an extension that redirects to old reddit.

You can opt out of the redesign in settings. I don't know how long that will last. Sometimes it shows the new one, but it's rare.

Yep, I’m aware of that. But the OP said they aren’t logged in. My tip was in response to that.
