I just tap the button "want to read" and it will be added to my "want to read' list right a way. I always skim the 'latest updates" first , then the comment list, sometime the recommend list in order to scan for good appealing manga , bookmark it and read it slowly later when I have time at night since I have too much job to do during the daylight T_T
Mine keeps increasing as well. Not to mention I know there's manga in my 'want to read' section that I've actually read or started to read and I haven't bothered to switch them. I also constantly read completed or even ongoing manga that I've already read or am currently reading, whenever I can't find anything else to read. I actually don't mind because I fall in love with the manga all over again. Sigh~ I'm stuffed.
Whenever I see someone begging for manga recommendation since the’ve run out of good manga to read, I think of my ‘want to read” list with more than 600 mangas still waiting for me -_-“ ( and it’s still increasing faster )
