i came across this page today. wow! what visual design and pop. the landing page is so vibrant and exhibits great contrast. the logo is pretty cool too. I guess its very mac like. they seem to be using mac style fades and icons.
i think it accomplishes several things that you find on a successful landing page.
- communicates what the site is about
- a link to learn more
- login if you are already a member
- sign up
- site wide navigation
i am sure there are metrics for a successful page, arguably the ultimate success factor is if someone signs up and becomes a paid member i.e. conversion rate.
