Several articles written by AlanF some time ago were the most intriguing anti-WTS material I've ever read. He just makes the most sense to me and on all of his viewpoints (JW-specific or not).
For the pro-JW side of discussions, I've always enjoyed Mark Sornson's posts on Usenet.
Some posters, like the one who calls him/herself Prominent Bethelite, I've never cared for (again on Usenet, but maybe the names are familiar).
