John Wagner offers some of the Chron.com bloggers a primer on the terminology.
We would have assumed Dwight Silverman would have given a quick lesson on the terminology and mechanics of the thing prior to turning the Chron.com bloggers loose, but he’s a pretty busy guy, so maybe a few Chron.com bloggers missed it.
They should read Wagner’s post in any case!
UPDATE: Right on cue, John McClain demonstrates that he could really stand to read the primer.
