Welcome.
In my two years as a non JW(before that I was just an average deist/agnostic/atheist/pantheist/) I have learned a lot. Watchtower's publications can certainly be a University education, that is if you dig the material they quote and the material that they overtly fail to quote.
Contrary to everything you are going to hear here, there are some of us who have a debt to the organization because it has pushed us to learn. Let me get started.
I trusted scientists and the theory of evolution but I didn't know why. Now I do.
I believed that religion was myth, but good. Now I am very ambivalent about it, leaning towards "religion is bad in general"
I used to somehow adhere to the belief that homosexuals were not quite equally deserving of some rights. Now I believe they deserve everything heterosexuals get.
I knew nothing about ancient history. Now I know at least some at an elementary level.
I knew nothing about the early chrsitianity. Now I know above elementary level.
I knew almost nothing about the Bible and the formation of the Canon. Now I know enough to give trouble to JW's and poke many, many, many holes at the holy book. (now I understand why they call it the holy book)
I knew nothing about cults. Now I do, especially about JW's
I used to believe that smart people can not easily be brainwashed. Now I have seen it with my own eyes.
I knew nothing about the history of the JW's and their leaders. Now I can give lectures to C.O. and D.O.s
I knew nothing about biblical times chronologies. Now I do, enough to offer $40,000.00 to any JW who can prove the chronology used to arrive at 1914 is well supported by facts and evidence.
Finally. I have learned, thanks to my study of the Watchtower and JW's, that Carl Sagan was spot on when he wrote:
The fact that religions can be so shamelessly dishonest, so contemptuous of the intelligence of their adherents, and still flourish does not speak very well for the tough-mindedness of the believers. But it does indicate, if a demonstration were needed, that near the core of the religious experience is something remarkably resistant to rational inquiry.”
