Review My Startup: Bookhu
Vindexus: First thing I noticed: "What Does It Do?" I wasn't really sure right away what it did. I found the "How Bookhu Works" box, but at first glance I thought it was an ad so I didn't even look at it.My recommendation would be to put a small tagline below your banner. Maybe "Book reviews broken down by gender" or something.That said I think the design is really good. I'd add some title attributes to the scores in the listings. It would be nice when I hovered over the 5 stars I could get a tooltip saying "3.4 out of 5 stars (from men)" or similar. Also the colored box with the percentage or men or women readers could use the same tooltip. At first glance I thought that was a rating out of 100. I know most people don't bother with tooltips, but do it for me?I was on this page: http://www.bookhu.com/breaking-dawn-the-twilight-saga-book-4... and when I clicked the "Select Bestseller List" it scrolled me down for some reason. I searched the source for an '<a name="menu">' but didn't find one.One the home page with the slider, the arrows are stretching to the edge of the screen, but the slider container isn't. Here's a screenshot: http://imgur.com/8JVjNWhen I use the dropdown to change the bestseller type, it disappears on the listing page and moves to the right side, instead of the top left. I'd keep it in the top left and put the list title right beside it.For advertising I'd have to say that you should definitely start a blog. You've got some pretty cool data and you could run some interesting blog posts. Maybe do some queries and find the words that are likely to appear in men's favorite book titles, but not women's.You could also do some sort of contest. I'd make it a "Men vs Women" thing to try to get people into it, and spreading it. Maybe a giveaway of a couple of books, or maybe Amazon gift cards.  Maybe pit a predominantly male book against a female book and based on which one gets more votes, give the gift card to a man or a woman. I know if you put Twilight against something you'd have a chance of going viral on Digg, Reddit or 4chan. Those people hate Twilight.Anyway, good luck with the site. It's well done.
