Well, actually, it's because all those manga are ongoing ones. So they update either weekly/bi-weekly/monthly, and I get restless if I don't start reading something. Haha. For completed mangas, I read those in one-go, or over consecutive days without jumping to another manga until I finish that one. XD so yeah. In a way, I am also like you. I like to write these updates so that even I can remember what I read during what chapter, coz often I only remember what happened but not what chapter it happened. Haha
