Opening articles in new tabs. Hard to upvote/downvote submissions later.

On hacker news, and some other sites, I right click and "open link in new tab" on every article that I think might be interesting. I don't want to up-vote or down-vote the article until after I've actually read it, yet, I'm unlikely to come back to the source of the headline minutes/hours/days later, search for the thing that I clicked on, so that I can up-vote or down-vote the submission. How could/should Hacker News or other sites deal with this behavior? (and please don't tell me to stop doing it, because I'm not going to stop doing this.)
