I dunno, FB apps are easy to do and fairly cheap to make. That's why there's so many of them. A LotRO FB app is a great idea, I just don't think this is the right one. I'd love to bring over my characters in a box on my wall, that would be cool.
I hide EVERY app on FB because I cannot stand the updates.
And too many work people are on my FB, I wouldn't want them to necessarily know I was logged in hehe. I'm really surprised actually about the login information, since a lot of people already have complained that this is visible in the social panel.
I'm surprised Turbine doesn't do more updates on its FB page that would then roll over to my page - now that I would support. But I don't get any LotRO notices, I belong to their group or page or whatever, but there's never a notification from there.
