actually it's a great thing to browse around mangaupdates... i'm an absolute glutton when it come to reading a type of manga i'm craving for atm and that site helps.

i'm too lazy to do things i have no interest of and it's so obvious when i don't comment in some threads at the front page haha. and who knows some people might have use of it, especially the ones who does not know how to use baka's search feature.

True that but even with its amazing features; there all still some manga you can't find because sometimes the appropriate tag hasn't been added or a series hasn't been given due attention. It's a user-driven website after all.
Like in my case...,I've been looking all day long for this damn oneshot but I know I'll never find it on Baka because it was really trivial thing and you obviously won't find a "stationary" tag over there. Sucks big time for me.

Stationery* typo

it is the same around here at mangago tho, the tags on the left are all based on users so there's some out-of-place silly tags even. (or a yakuza in a slice of life manga WTF...) so i just decided to create my own set of tags bec. my OC-ness will kill me if i won't take an action haha.

at least in baka the people adding the tags are more matured and reasonable but ofc a minor tag like stationary would really be hard to find haha. also, about the stationary: unfortunately, i only remember the mangas that impressed much on me and we don't have something like mangago list years ago. i do barely remember the plot, there's at least 3 mangas that popped out of my head with the similar pencil design but the title is being elusive to me.

Yakuza in a slice of life sounds pretty decent too lmao.
And thanks for trying tho...,it's another manga down the seven levels of sea for me....
I have such a rotten memory....if I was only able to remember what the main story was...
