I have two JW sisters and a JW mom and all them have computers with high speed internet. My mom barely knows how to use it, buy sisters are quite a whiz at it. They use for everything! But as far as for spititual things and connecting with other JWs its still a no no.
I remember when I first got a computer years ago and I hooked it up to dial up ... the only internet we had back then. My sister came over to see the new fangled contraption and we decided to see if there were witness websites online (we heard you could print off the scriptures for the current meetings already prepared by someone (obviously I was still a JW back then). Anyway, we did and search and some 'apostate' sites came up on the search page like Freeminds and the little snipit said something about the JWs being a cult.
My sister threw her hand over eyes and was screaming 'get it off! get it off!' I was the funniest damn thing I had ever seen! I showed her the miracle of the 'Back' button and how we could modify our search by typing "-cult" she was okay, but I still remember her reaction and have wondered if she would do the same thing today.
