We set out to build a better Goodreads a while back called Helloreads (my wife thinks we didn’t differentiate our name enough but whatever). It never seemed to get traction probably due to the monopoly and network effect of Goodreads. We thought and still do that Goodreads user interface is terrible, the site is slow, the reviews are too volatile. The one thing that we truly could not compete with them on is the data…
The front page should say something about specific books, something that draws you in! Something from the site itself. And put that book recommendations button higher up (it's not visible on first view for me). :-)
Something that makes you begin browsing and using the site to get recommendations. Then in standard style, somewhere down the line you'll hit a snag where you have to register to use certain features, like commenting, liking, etc.
