As I've been designing the marketing pages of my app I've drawn lots of inspiration from lots of different sites. And everytime I bring up one of theirs, I'm struck by how cramped and jam-packed full of extraneous information they are now.
If you compare http://basecamphq.com to something like, say, http://checkoutapp.com/ or http://sifterapp.com/ it just comes across as too much.
