They eye of the beholder...
I am not hugely impressed by the artwork of the site but it is definitely not the worst site that I have seen
It's not the worst site I've seen, but I've seen better landing pages designed as weekend projects by people who then post on here with all the appropriate "I'm not a designer...can you give me some help please" questions and get advised to commission a freelancer who knows a bit about colour schemes as well as having the time and skill to add polish. For a major launch from a massive corporation whose products are (theoretically) driven by good UI and a consistent corporate image http://www.salesforce.com/assets/pdf/misc/SFDC_StyleGuide120... it's quite shameful.
*reserve price if you wanted to buy at auction earlier in the year was $800,000
The flat grey at the top. The logo. The badly resized bullet points with jagged artefacts. No sign of the original salesforce logo. All the fonts are a little too big, but not in a pretty way. The pricing page.
I guess there's something to be said for simplicity, but this site looks like a Frontpage template.
