They already have encouraged people to use the downloaded magazine whenever possible. It was in the initial letter announcing that the pdf files were available. Not really pushed much since, but pretty much nothing is since there are no more lengthy announcements at Service Meetings anymore, either.
BUT there is ONE DIFFERENCE between the pdf and the printed magazine. The pdf ONLY has the study articles. The extraneous BS articles (such as the June 15 WT's article about last year's annual meeting and the introduction of the "generation" change) are ONLY to be found in print, not online.
