It does make sense. If you are hiring a lawyer for his or her advocacy skills, wouldn't you ideally like to hear (or see) some examples of the lawyer in action? Event planners routinely ask for samples from prospective speakers.

Might a podcast be a way to create that kind of "sample of work" for prospective clients?

'Of the 80 cases before the Supreme Court last term, 25 involved questions directly affecting businesses, according to data collected by Goldstein & Howe, a Washington law firm specializing in Supreme Court litigation. While 33 cases raised questions of constitutional law, 45 involved the interpretation of a law, one involved an interstate dispute and one involved a dispute between a state and the federal government.

That was a typical year, said Thomas C. Goldstein, a partner at the firm. The Supreme Court's caseload is made up of "relatively mundane questions of federal law, mostly about statutes, not the Constitution, that are important to little corners of the legal universe but are not on the hot-button social issues of the day," Mr. Goldstein said.

"It may be that abortion is the most important question that the court decides," he said, "but it's close to the least frequent."'

The Slate article, authored by Professors Gellers, Luban and Lubet, contains an extensive discussion of the caselaw of the 'appearance of impartiality' standard.
