Hi Sarah, I am working in marketing myself and am happy you joined the team. People with your background are crucial to adoption of the project.
David Irvine and his people are very smart people and some of the few who don’t only understand technical stuff, but also see things from a broader perspective. Success of the project in the end is achieved thru effective communication.
The majority of people first check our website and therefore it is crucial communication on the mainpage of the website has to be understandable for everyone.
I think the website needs editing in order to pass our message on to the crowd in understandable terms.
I wrote the post below to help make what Maidsafe does, more understandable.
I hope you take notice of that post and that it will help you in your efforts to get the Maidsafe word out!
Thanks and Good luck with everything 
André
