I agree with the others re the design. After loading your page it takes a while to work out what the site is actually about. The mass of text is quite confusing, and I think you need to better explain the relationship between "resource" and "sticky".
Interested to see you use GWT for this, I know it can be difficult to make anything look good with it. Making the whole site javascript seems to make browsing quite slow, cant you speed it up a bit somehow?
just a few thoughts, good luck!
