Just for fun: This suggests to me that Luskin is a thin-skinned goofball. Mr. Jeffery Upton, Esq. may direct legal nastygrams to firstname.lastname@example.org.
Addendum: Jonah Goldberg sympathizes with Luskin on the grounds that this is just a "classic new-to-the-web blunder." Uh, no dude. Writing a thousand word reply to a flame is a "classic new-to-the-web blunder." Threatening litigation against a blogger who called you a "stalker" is totally f*ing nuts.
