Tweaking and tuning forever

I've been working on our front page lately. It's the page where the critical eyes come for the first time, "what a useless service" already echoing in the mind.

Someone once said this about communication: If you throw a ball to a friend, she'll catch it. If you throw two, she'll probably catch one. If you throw three, she'll miss them all. So I've tried to narrow our message to one. It's difficult. We tell that this service is here to remove the common cold. We utilize Facebook status updates, Twitter and similar (Why there is no single word for these, why can't the microblog be commonly understood?) by collecting medical symptoms.  And in the end we warn users about incoming colds near their homes or workplaces. Where's the math of 1+1+1=1?

One page, ten seconds and five words is a too long sentence. I like easy answers, I tried to find them, but I think there are none. Sometimes the sky pieces of the puzzle must be added slowly, one by one. But in this puzzle they also have to be constantly removed.
