I think it needs to be said web developers are humans. They read well written, targeted copy just like anyone else.
The headline:
Get your Flash Back! is not benefit driven, nor does it address your target audience. Frankly the headline is more like the stuff copywriters get accused of rather than what they actually write.
The testimonials section needs a redesign. First, it only shows one testimonial per page view. Next, there are no last names, which make them all but worthless. Finally, they are really too short. Change to a non-gimicky noscript box, scrolling if need be but put in several credible testimonials.
The site suffers from a serious Web 2.0 infection. Symptoms include a phobia against informative copy. I suspect this will need to be treated in order for any advice such as is provided here to "stick." In other words, the decision maker has got to get over the extreme image consciousness and engage in some A/B Split Run testing.
My suggestion is to show stakeholders sites like
Jewelboxing, designed by 37signals. This is a happy median between where you are on design and where you need to be.
Once that happens, try collapsing the several pages into one, informative one. Go from getting started, through Why do I need this? to Two Simple Steps. One page. Make your button into a "call to action," and even more buttonlike.
Ban the designer of this site from ever using tabs, until they can write an essay on the proper use of tabs. (Citing user research).
