This will be of much more interest to bloggers than to non-bloggers, but Atrios, one of the best and biggest of the blogosphere, has an excellent “Occasional Reminder” about links, traffic, and other blog-related matters here.
Needless to say, it’s a must-read. (By the way, I enjoy getting e-mails from, and getting to know, fellow bloggers out there. But of course, The Reaction is much, much smaller than Eschaton!)
