Reddit's going that way though. I frequently like to browse subreddits in incognito mode. Reddit's now A/B testing a "feature" where they force certain sessions to log in, or else they can't see anything.

Profiles are now being transitioned to a social media profile, where it's more like a MySpace page. You can get around it for now (add "/overview" to the end of the URL), but it's default for a lot of users' profiles.
