First impressions are extremely important in anything.  They are the basis for future expectations from your customers.

Springpad is an online notebook site that is "designed to simplify".  Does the above screenshot taken from their How It Works page seem simple to you?

Not a very good first impression in my opinion.  A site claiming that it's "designed to simplify" has super information overload on the same page as that claim.  Simplified?  Not so much.

Think about your company's first impression.  Is it what you're going for?
