Your design needs some work. Looks washed out and a bit empty, but its a good start.
The comparison chart is a mess (no offence). even though you've tried to spruce up the data, it does still look like a lot of data to take in.
Just a little tip for comparison charts. Your data should be slightly more highlighted compared to the rest, to give a subtle "OMGOSH We are so much more awesome than these other guys" feel.
you can do this by either making it more bold, larger or using a brighter colour.
You need to look up some examples of chart formatting. Find a way to separate the table rows and columns (Like an alternating colour for example).
In terms of the chart, there is too much data to stomach in one "eyeful". You should perhaps add a horizontal break saying something like "Not enough? Here are more reasons why we are better than our competitors."
With the more important data like Price, space etc in a couple of rows above it.
Its all about grabbing attention and people like bite-sized chunks first, lots of data later when you have hooked them in.
On a similar note the whole page needs a way to be horizontally broken down. Its just a mass of information presented in one lump.
If you take a look at your competitor's website, you will see the difference:
http://wordpress.org/
You can see how little text the user is presented with.
Another point, you have overused the arrow bullet point. Well, not overused as such. There is no need for it to be in the comparison chart. But even still its too bold compared to your titles. Draws the eye away from the text.
I've always maintained that you need to keep the cleanest and minimal look to be a success on the web.
Hence:
Google vs
Yahoo/
MSN
Facebook vs
MySpace(Although myspace was more an issue with letting their users go mad with their own page, but it still validates the argument)
Hope this has helped and didn't mean any offence by what I said, just getting straight to the point.
EDIT: Another point, there is no need for you to be restricting yourself to a blog style design (everything is bounded by a finite sized, centre aligned box). For this type of site it isn't suitable. Spread yourself out. You can still have your content aligned to the centre in a finite box, but there is no need for all that blank space around the outside.

Even a subtle touch to the background can make a massive difference:
