First-pass landing page review

Page copy:
[PAGE COPY, headline through final call to action]

What a first-time visitor should do after reading: [WHAT A VISITOR
SHOULD DO]

Read this as someone seeing it for the first time, with no context
beyond what's on the page. Answer:

1. After the headline and subhead alone, what do you think this is?
   Is that correct?
2. Is there a sentence where you'd have to stop and reread to
   understand it?
3. What question would you still have, right before you'd need to
   act on it?
4. Is the call to action clear about what happens after you click it?

Answer as the reader, not as an editor. Don't suggest rewrites yet.
