Because I am too damn lazy to write reviews (seriously, folks, it's hard to read a manga 3 times in a row unless it is an epic!), I will provide topics for discussion (just as good, in my opinion).
I was staring at my Yaoi shelf today (I group books by publisher), and I was noticing the ones with dust-jackets vs. the ones without. My personal preference is no-jackets because I believe in practicality over bells and whistles. It's easy for me to pick up one of my Be Beautiful books and start re-reading just because of its basic quality (huh?). It's true, when I pick up a book that has a dust jacket, I usually just end up flipping through it, taking off the jacket, putting it back on, and not reading the book at all. The bells and whistles of the manga should be a stellar translation, and the title itself. Have you ever bought a manga just because it looked pretty? Did you get burned?
When I pick up one of my jacketed books, I tend to focus on its quality rather than its contents. I know the publisher wanted me to get it because it dolled it up so I would THINK that it's a good buy. The only publisher who has the Dust-jacket down to an art is DQ. The gorgeous jackets accompany the flimsy and gentle books quite well, whereas June's jackets clothe a pretty large, heavy, and stiff tome. Same with 801, except smaller.
While this discussion is all very nit-picky, it's actually what companies consider before marketing themselves. Kitty Media and Be Beautiful, being two of the first English Yaoi companies, had no idea that fans might want the pretty dust-jackets and colour pages. As for this fan, I can do without.
