In conjunction with Movable Type 3.0, they are introducing a new service, “TypeKey(TypeKey Authentication Services)”:http://www.typekey.com/. As is typical in the blogosphere, merely the “hint( More TypeKey Information)”:http://www.movabletype.org/news/2004_03.shtml#000926 of how it will work has elicited a number of strong opinions both “for(TypeKey?

And “questions(Questions for SixApart)”:http://blogs.law.harvard.edu/crimson1/2004/03/20#a1327 and “more questions(Questions for Dave Winer)”:http://www.plasticbag.org/archives/2004/03/questions_for_dave_winer.shtml and “even more questions(Six Apart’s FAQ on TypeKey)”:http://blogs.law.harvard.edu/crimson1/2004/03/23#a1396. However, at this point, since it has received the “endorsement(Movable Type 3.0 and MT-Blacklist)”:http://www.jayallen.org/comment_spam/2004/03/movable_type_30_and_mtblacklist of Jay Allen, whose extraordinary tool has become an “essential part(Comments on Comment Spam)”:http://www.libraryplanet.com/2004/01/spam of the operations around here, I can pretty much assure you that I will be an avid TypeKey user. But I was really struck by the whole issue of anonymity. This is my personal belief. There is no such thing. You can take steps to limit your exposure by signing up for an “anonymous e-mail account(Will anonymous e-mail become a casualty of war?)”:http://www.cnn.com/2002/TECH/internet/02/13/anonymous.email.idg/. But if you pay for it with a credit card, it means they have a record, which can be obtained via a court order. If you use a re-mailer, you may be safe, but there is no “guarantee(A Brief History of anon.penet.fi – The Legendary Anonymous Remailer)”:http://www.december.com/cmc/mag/1997/sep/helmers.html. And, of course, everyone who comments on a weblog leaves an ip address behind. Which, is not necessarily that difficult to “track down(Output from ARIN WHOIS)”:http://ws.arin.net/cgi-bin/whois.pl. So here is my advice: decide what level of anonymity you are comfortable with, and conduct yourself accordingly. “That(whois record for: libraryplanet.com)”:http://www.easywhois.com/index.php?domain=libraryplanet.com&next.x=27&next.y=2 is what I do.
