The text links at the top ("Home", "Social", "Website", "Mobile") aren't spaced far enough apart for me to parse them as different links. Coupled with the "Web Social Mobile Monetize" text in the header graphic they create an overwhelming impression of jargon which dissuades me from wanting to read the actual text. You could probably link to most of those pages from a single "about us" page and keep the main page cleaner and your signup funnel more focused.
Nobody reads these days, so I think having such a mass of text is a bad idea front and center. The stronger bits of the page are further down. Unfortunately, everything below the green bar rolls offscreen on my 13 inch Macbook, so the immediate impression is simply of a lot of text in a fairly unreadable color scheme. The strongest explanation you have is ("Web + Blog + Social") imho, although you might want to double-check that the wording resonates with your target market -- people might be very clear that they want a website rather than a blog and calling your system a blog might put them off.
Most powerful inducement to checking out the CMS would probably be seeing it in action. Drupal lets people play around with a live version that gets reset every now and then. Could you do something similar, so that people can see and play around with what they'll be buying?
All suggestions intended constructively. Good luck with the business!
