In a comment, the poster adds, "The teen bloggers on Xanga and LiveJournal right now might be the adopters of Blogger and Typepad down the line. Right now, searches on Blogger are about one-tenth of Live Journal and one-fifteenth of Xanga. Typepad doesn't have enough searches to enter the fray right now."
But I'm especially amused by the comment by "Andrew", which claims LJ ain't all bad 'cause people like jwz use it. Heh.
