I did. I was at least two kinds of nerd when I made the connection.
I'm not up-to-date on the latest developments but as long as the characters aren't completely unrecognizable these should still be good.
The thing about Virgos is they want everything to be just right, and it starts from a young age. Virgos are the type to have problems pooping anywhere but at home. They hold it in, health warnings be damned, and from this they learn to ignore their bodily complaints. They learn to push themselves to the limit. Pain, fatigue, or emotional turmoil? A Virgo will clamp down on those things without thinking. That has its good points and its bad points. On one hand, Batman is the definition of heroic willpower. On the other hand, he's got no work-life balance at all.
Batman forever chases after perfection. His perfect childhood was shattered when his parents died, so he pursues a vision of a Gotham without crime. A perfect Gotham, in other words. He's trained himself to the peak of physical and mental ability and he trains others toward the same perfection. He's crazy-prepared because he wants his fights to go perfectly and he's hard on his relationships because he holds everybody to his own unrealistic standards.
The Riddler isn't quite as extreme, but he also displays the Virgo traits of intellectualism (because nothing can be perfect in ignorance) and constant testing. Remember, the symbol of Virgo is that of a virginal woman who separates the wheat from the chaff. You can find Virgos everywhere searching after purity, or at least the best of its kind. The Riddler searches for his intellectual equal: Batman searches for people he can trust.
Both Captain America and the Joker serve the truth, or at least what they think is the truth. Cap's idea of it is tied in with Justice and the American Way, so of course he's a patriotic hero. He charges straight into battle, because anything less is somehow dishonest, and he has complete confidence in his cause. After all, who can deny the truth? Who can stop the truth? There's not a lot of self-doubt to Aries types. It's probably why they look so young and behave so outrageously.
Joker, meanwhile, serves darker truths: Anyone can become like him if they have just one bad day. The world is absurd, and the idea of a man in a mask (a man in a mask!) fighting crime is simply laughable. The truth is that Batman is a criminal like everyone in his rogues gallery. He has that pesky no-kill rule, but really, how can anyone expect justice from a man who doesn't show his face?
The Joker would very much like Batman to kill him. It would show the Dark Knight for what he really is: a brute, a bully, a man who believes that might makes right.
