what's taking soooo long?

Most of the mangas I'm reading right now are taking so long to be updated. How I wish it wasn't so but beggars can't be choosers.

Bleach
Naruto
Skip Beat
Kimi ni Todoke

And that's just mentioning a few. So, to alleviate my thirst for manga, I'm re-reading a lot of already finished works. Right now, got Mekakushi no Kuni opened to quench the thirst.
