@Tsukinotaku The reason that Yuri vs Shoujo Ai is pretty annoying as a tag system is that a huge amount of 'shoujo ai' manga is just Yuri manga that hasn't advanced far enough yet to be 'yuri'.
This means that mods and users have to keep looking at Shoujo Ai manga for every new chapter to see when the relationship turns sexual.
Since there are very few manga that exclusively focus on non-sexual relationships, it makes more sense to assume all new GL relationship manga is 'yuri' (especially since most authors publish these as 'yuri').
They are going to kill the Shoujo Ai tag in the near future, or at least they said they were in this year's plan. A lot has come up since then so they might be too busy for that right now though.
