What is a "concern troll"?
Atrios and commenters provide the answer. What other questions should be answered on blogging lingo? I imagine you know what a "purity troll" is by now. And you are all aware of the the "pimping" and "whoring" rampant in the blogs. A veritable Sodom, not to mention Gomorrah.
I claim authorship of one term, but I think both the term and the practice really has not caught on - "linky thread." This is an Open Thread that contains links to other posts from other blogs that you feel merit attention. Now a staple at daily kos and other sites.
My favorite insidery blog phrase was "Holden gets a pony." I think everyone knows that story, but if you do not, Google and Wikipedia have it. Just kidding, one of the leading atriots, NTodd, quoting athenae, explained:
