I don’t see the post voting mechanism having much effect on bubbling. The problem with a filter bubble is not being aware you’re in it. If you’re aware, then it’s not a filter bubble. I think this comes from architecture, from Twitter’s presentation as one giant global conversation, as opposed to every post being made in the context of a distinct topic-based community. On Reddit you intentionally navigate from place to place, subculture to subculture. You’re less likely to mistake a certain political attitude as the new global norm, because you develop an understanding of which views and attitudes are common to which sub. Even if you only look at the front page, each post is clearly labelled as having come from a particular sub. Twitter in contrast presents itself as one single context for everything in your world, pushing the false idea that what you’re seeing is representative of what other people are seeing. That’s what’s behind the filter bubble effect, I think.
