LEADING THE DAY: Chairman Lamar Smith introduced a manager’s amendment to the Stop Online Piracy Act that addresses some but not all of critics’ concerns about the bill. The proposed changes include: clarifying that the bill is aimed at foreign Web sites, nixing language that would have required redirection from rogue sites, clarifying that service providers don’t need to block subdomains and narrowing the definitions of some key terms in the bill to focus on bad actors. Markup on the bill is scheduled for Dec. 15 at 10 a.m.

Sherwin Siy of the public advocacy group Public Knowledge, said in a statement that while the amendment makes improvements to the original bill, he is still uneasy with the measure’s focus on Web site blocking.
