Good point, I hadn't thought that some people are using the upvote button effectively as a bookmark button. Interesting idea the unified upvotes+bookmarked view. And your comment raises the question, what does an upvote mean? Why do people upvote? There may be lots of strange reasons. But whatever upvotes mean -- whether it means people want to bookmark it, or people find it valuable, or people want to bring something they disagree with to the attention of other people -- an upvote is a rough signal of "this should get more attention". The whole concept of a link aggregator like HN only makes sense if we assume that upvotes can be interpreted as a proxy for what people think deserves the attention of other users.
