Menacing DOG's -Another Secret- (a spin-off of Nogizaka Haruka no Himitsu) has been added in English. Still not sure how they decide how frequently to update things, since this one already has two chapters and chapter 3 is coming up this week.
Maybe not popular enough? Could also explain why there are virtually no updates beyond the first chapter.
@shark Mosaic Roll is not in the first post right now. Maybe that replaced Log Horizon.
They're doing a monthly schedule for pretty much all the series, so barely anything is past the first chapter, sadly. On another note, both Accel World and Sword Art Online: Fairy Dance have been added in English.
I wish they had updated their chapters more and such.
Regardless, it seems mangabox is the most competent entry of these free ones, while shueisha meager offering with the shonen jump line seems like it isnt really going to be facing any pressure from these free alternatives.
