the one concern about going pretty much all electronic is I still think a lot of the money is 'made' because in essence the WTS is a multilevel marketing publishing company. If there is no need to pick up paper copies of WTs and Awakes and provide a 'suggested donation' at the KH, and then hopefully collect some additional money from the people while in FS, a source of income will dry up, unless they have a guest and member sites on the internet and maybe make some $$ there.
The WTS seems to be making most of its money at least in the US on real estate these days, I guess the paper goods will have to continue for the global south where internet access is still not a given.
