James Joyner echos my month-old hypothesis on weblog comments, writing in response to the decision to shut down comments at The Command Post:

Unfortunately, there seems to be a strange variation on the Gas Law with regard to blog comments: As blog readership expands, the quality of comments declines geometrically. When OTB had 500 readers a day, the vast majority of the comments—whether from people who agreed or disagreed with me—were quite good. With readership in the 5000–10,000 range, most comments are crap. Reading—let alone policing—the comments gets to be more trouble than it’s worth.

For my part, at least, I’ve been pleasantly surprised by the lack of acrimony and vitriol since enabling comments here at Signifying Nothing, but—then again—our little corner of the blogosphere only attracts about 1/40th of James’ daily readership.
