I live and work in Indiana, so here's my two cents...
I disagree with the law, since I think the First Amendment of the US Constitution already ensures people have the right to practice their religion. With a law as controversial as this, it's almost certainly to find its way to the Supreme Court, where I'm sure it will be overturned or gutted because of the discrimination issue.
While I believe boycotts are rarely successful, if people decide to boycott Indiana, I'm not going to dissuade them. Maybe my rent will go down if fewer people want to move here ;-)
