I'll second the suggestion about losing the "Hey I'm Stu". By all means introduce yourself on a secondary page about the company (it was via your Twitter account I saw you'd put together some other pretty neat looking webapps which might be worth drawing attention to) but the home page should be all about answering the "why would I want a Kroud?" question.
I've revised the home page with "Why use Kroud". I think a personal touch to a home page really helps, and I've been advised a lot in the past to do this more often with my products. So I've kept my face, but asked a very valid question. Why use Kroud!?
