First off, great design and layout, very clean and pretty too. It compliments twitter well. However, it's not clear to me what the service does. The first feature listed on the 'what you get page' says: PubliciTweet is a social media marketing tool that helps you leverage those followers with unique campaigns and tools to track your success.
This works more as an opening tagline and might be better suited to the homepage. From the homepage, I get the idea that PubliciTweet is a service where I can queue a series of tweets at various intervals . PubliciTweet then tracks and graphs which tweets by measuring clickthroughs perhaps. When I click 'learn more' - I don't learn actually learn any more. Maybe an in depth description could go here explaining the guts of it or a video demo.
