I think a lot of people may be less technically proficient, and especially if they are trying to perfectly replicate the Reddit experience it just isn't there yet. There are lots of things possible to do - use multiple browsers, each logged in to a different account, or the same with apps, etc. But one issue I could foresee with that is that anytime you want to block something on one (like a magazine that speaks in a different language), you'd have to replicate that with the other.
