That depends on whether OP keeps reading this/other stuff in this thread. 
Also, you’re right that people wouldn’t find it if they only look at the book clubs, but if they search the title, it’ll show up.
This one used to have the title, but it was changed to be a thread for the OP to read more than one manga. So they changed the title.
I also meant this thread: デンジはまた読んでる — denji’s reading thread
I agree on the category, depending on if they want to start their own club or just read it by themselves.
I was also just trying to say why I think they did it, even though I’m not OP. 
@anon12500920 go add the titles in Japanese so they show up in the search
