This is a brave and interesting idea, Skittles have replaced their entire corporate website with a series of links to various social media sites. The homepage is the twitter search page of everything that people are saying about the brand right at that very moment.
'Products' links to wikipedia, 'media' links to youtube and flickr. 'Friends' is the facebook page and 'contact' links to a contact form on their own site.
Interestingly, 'chatter' is the same as 'home' currently, suggesting that the twitter feed homepage is temporary. Perhaps this is a stunt to get twitter attention? Lord knows it's so hot right now.
A lot is currently being made of how people are hijacking the skittles twitter page to include profanities etc, but this is temporary, and if anyone from the skittles marketing team is reading this, you should tough it out as this approach will probably pay off for you in the long run.
The idea is quite extreme at the moment, but what is good about the
idea is that it is flexible. There are not massive production
implications of changing the flash panel and shifting a few links around. Probably in a week or so you will find a 'proper' homepage going over the top of the site, if only to link to the other environments.
Bravo to whoever sold this in, as it is going to be big.
