He apparently had the support of the liberal cardinals, dose large amounts of work for the poor, is rather humble and lives humbly even when luxury is available. Has a degree in chemistry. Is from Argentina so he's also our first Pope from that side of the world. And the first Jesuit.
And he just sounds like the kinda guy the Church needs right now. Like here's a bit on how he handled his home bit.
"Bergoglio often rode the bus to work, cooked his own meals and regularly visited the slums that ring Argentina's capital. He considers social outreach, rather than doctrinal battles, to be the essential business of the church.
He accused fellow church leaders of hypocrisy and forgetting that Jesus Christ bathed lepers and ate with prostitutes.
"Jesus teaches us another way: Go out. Go out and share your testimony, go out and interact with your brothers, go out and share, go out and ask. Become the Word in body as well as spirit," Bergoglio told Argentina's priests last year." - (Link)
He is by no means perfect. No one is but you know he might just be what we need right now. And he might actually turn out to be a liberal (by pope standards) and if not that, a tolerant pope.
