This complaint was raised by a lot of television critic-bloggers during the first run of Netflix releases (House of Cards and Arrested Development in particular). I think it's ludicrous. If you and all your friends really think that weekly spoiler-free discussions are the most important thing, then just agree to watch 1 episode a week. We already have to deal with this sort of thing with weekly releases, if someone misses the recent episode (or someone else is catching up with earlier seasons on VOD).
