Agree with too much writing. For example, "PowerGrabber is an invitation manager. It captures the addresses from your inbound and outbound emails, so you can invite the people you email to join your LinkedIn network." is too long for a headline.

Shorter version could be: "Easily invite more people you know to Linkedin", or something like that (you surely know the value proposition better than me ;)

And then but the most important things in bullets: the price, the fact that it's a Windows download, etc. Edit down that text, shorter is better :)

I agree as well on the too much writing. People don't like to read that much. I think you should reduce your copy on this page to a few (in my experience people tend to like groups of 3) of the highest priority issues and then link off to another page for each section should the prospect want more information.

Thanks for the feedback. Yes PowerGrabber is intended only to do one thing - allow you to expand your LinkedIn network. I'm thinking that focus and a minimal feature set might be a good thing.
