Legal Blogs
Some standouts:
SCOTUS Blog A great source for updates on the Supreme Court, maintained by one of the leading Supreme Court litigators.
How Appealing The premier appellate law blog, focuses on the federal circuit courts of appeals and the Supreme Court, but also includes short summaries of any other interesting legal news. Maintained by a solo appellate litigator and one of the most prolific blogs I have ever seen.
Lawrence Lessig A well-developed blog on the work of Prof. Lessig and affiliates. Prof. Lessig is one of the leading IP and Constitutional Law scholars.
Sentencing Law and Policy Blog Sentencing is the hottest thing right now. This blog is quite comprehensive.
Balkinization A thoughtful blog by a liberal Constitutional Law scholar from Yale, Jack M. Balkin.
