i noticed that too. I sure didn't read much but I have a lot of spare time now since, lol college is over. There is a lot of manga out there but /a/ never talks a bout it because it would be like 2-3 people that even know about it.
however, /a/ does like to talk about a few titles here and there that get a lot of readers just because its posted often. I think it's good for /a/ because /a/ would then just be /a/ - Anime.
