The fine folks at Samizdata.net are compiling a Blog Glossary to help people get up to speed on some of the slang and verbal shorthand used on blogs, especially "warblogs".

I actually contributed a few definitions by email: both definitions of "permalink", and the second and third definitions of "warblog". I also sent in a definition of one of Glenn Reynolds' favorite expressions, "Rope-a-dope" ("noun. A strategy of pretending incompetence in order to tempt one's adversaries into ill-considered action") but they didn't use it.

I love stuff like this. For more -- arguably 'way too much more -- see the Jargon file maintained by Eric S. Raymond.
