Which browser are you using? It only needs an applet for browsers that can't support the clipboard api (unless it detected it wrong, which is possible).
Very true. That's how I knew the meme. I saw it on reddit which I also frequent. However, that doesn't mean we should introduce them here. They don't add to Hacker News discussion.
And I totally agree with you, I just actually couldn't resist. I was ready to face some downvote (and I have been served…). Apologies.
However there already are some links on HN which leads to reddit style discussion, like the recent link to the "Great HN parody". I think it may be okay from time to time as long as it doesn't flood the discussion.
