Review my app: Wappr
techiferous: Some design feedback:* "What is Wappr?" -- the font size and style should be the same for the whole phrase.* The slidedown should be much smaller.  Wrap it in a differently colored box with rounded corners (perhaps a background darker than the page background).* Add another color besides the light blue.* Increase the contrast on your Wappr logo (either black letters or darker blue background).* You have too many font sizes.  I would pick three font sizes and stick with them (and make sure the font sizes aren't too close to each other).* The "sign in with twitter" animation when you click "vote this" is really cool.* Make the previous/next/page links more prominent (or change them into image links).* The twitter icon at the bottom of the page needs to breathe (it touches the fat footer).* I really like the light, simple, zen-like feel of the design.* Your fat footer spans the whole width of the screen.  If your header did the same it wouldn't feel like the page is completely squished into the middle of the screen with unused space on the edges.* I like the subtlety of the divider separating the list from the header.
