Okay, here's some feedback -

What I Like - The feature set and the clean look

What I cannot find - A demo on the home page itself. Not be required to click a "live demo" button

What turned me away - The pricing strategy. As a dev, I love the pricing. As a user, I dislike the pricing. Just give me a flat price and call it a day. Especially applicable for small blogs, newbies and people who don't yet have traffic. That breakdown just indicates to me that I will have no idea what my end bill would be like, especially if my blog starts gaining any traction.

That pricing page also probably limits your audience to a small subset. I showed your pricing page to someone non-technical and they pretty much lost any interest.
