I can't agree with the 37signals.com screenshot being described as "the user shouldn’t feel too overwhlemed. Everything has a bit of space and isn’t fighting for attention."<p>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.<p>If you compare <a href="http://basecamphq.com" rel="nofollow">http://basecamphq.com</a> to something like, say, <a href="http://checkoutapp.com/" rel="nofollow">http://checkoutapp.com/</a> or <a href="http://sifterapp.com/" rel="nofollow">http://sifterapp.com/</a> it just comes across as too much.
