Yeah; popping up the card when you're on a link of the card itself is a bit silly.

@Vitenka: I don't think that's what he's talking about. You're right, though, giving a popup of this card itself on this page isn't very sensible.

@Circeus: They're not as useless as you think. The popup from the card name of a card mockup includes info on the comments. Eg this card's popup says "1 comment about 16 hours ago by Vitenka". If I'm looking at a card in a visual spoiler, say, I often want to see if there's been any comments on it at all; if there's been any comments in the past couple of days; or whether I was the last person to comment. The info in the popup below the card mockup itself tells you all that.

The popups on links saying "N comments" themselves aren't providing much new info in that case, I'll agree.

One other thing to note is that when I get any time to work on Multiverse, one of the next big features will be decklists, which can potentially include cards from a variety of sets across Multiverse. When that comes in, the popups will include status indicating whether you have this card in your current decklist, and a button to add it to your decklist. So although they might be useless at the moment, they'll become more useful later.
