I think their landing page needs to indicate how they are different from Evernote. The ability to 'find cool new stuff' is intriguing - a bit like Stumbleupon + Evernote then?

Also there needs to be a way to contact someone and/or ask questions and/or provide feedback. An Olark tab would work.

I was thinking the same thing. Given I use Evernote to save pretty much everything, why would I need a separate service that does the same thing?
