First impressions:

1 - I should be able click around the steps on your carousel animation (above the learn more and sign up buttons). 2 - Bottom right, tweet is bleeding out of the box 3 - Will your plugin annoy users of your clients' blogs? (e.g. are there obnoxious rollover popups, etc) 4 - As others mentioned, the design has an air of cheap template. It's mostly because it makes excessive use of bright color and it's too busy. Instead of packing things like "breaking news" onto the homepage, space things out more and give widgets more breathing room.
