The contrast in his body language compared to Benedict is dramatic - he looks like a genuinely humble and honest man. Asking the crowd to pray for him before he gave the blessing is either the work of a PR genius, or a very promising sign of things to come.
He's a 76 year old cardinal, so I don't expect much from him on gay rights, but, as evidenced by his choice of name, he seems to be serious about fighting poverty, and that's a very good thing IMO. He's also not been one of those career bishops who just hang around the Vatican, instead he's been actually running a real diocese and remained in contact with real people. That also can't be a bad thing.
Finally - as the first ever Jesuit pope, I think he just might have a different take on the job to the last few we've seen.
For now, I'm pleasantly surprised!
