I've made my list of my own works, classic loves, and what I'm reading now. THAT I love. However, I don't love putting up public stars on books. I know I'm truly missing out on the spirit of the site. But this is what comes to mind:

Do I put a star on the belly or not? Did a reader star my belly? If so, with how many stars? Is my belly even that big?
I can't do it! My compromise is to use goodreads as my bookshelf to review what I've read. Rarely will I do reviews.
If you want to know what I really think, you'll have to get your hands on my journal. There you will find my world belly view, those who have stars upon thars, and those that, in my opinion, don't. Because come on, we all have our own opinions, right? I just prefer to keep the bellies covered. If my little words, or absence of stars, ever hindered an author from writing their next great work, it would be a great sadness. On the flip side, I can't fling stars without merit, either.
So, at this point, for me, if you pass me on goodreads, let's just say I'll shake your hand, no matter the stars on your belly or mine.
