Who designed the graphics for your web app, and where did you find them?
radley: Can you find someone from a local college or Craigslist to build Google? Prolly not. Same goes for Vimeo's design. It may seem really simple and easy in appearance, but that's the result of clever design, not chance.It's really hard to hire a talented creative director if you know nothing about design. You may want to consider working with a design studio for now, just to learn the ropes and gain a higher appreciation. Poke around design award websites or places like deviantart.com to find one.
