I don't know why people freak out over the whole Thor/Jane thing. It's not like Thor is ACTUALLY a title rather than a name. Before he ever picked up the hammer, his name was Thor. When Thor briefly gave his hammer to Masterson with the intent of remaining in Asgard with Sif, his name was still Thor. He simply renounced the name Thor because he was feeling depressed and melodramatic after suddenly becoming unworthy. It's now a title only because he renounced it and personally made it a title himself. At least that's what it seems like to me, it's very possible that it's been established via recton that it was ALWAYS a title and I'm simply unaware of it.
