As a random user that sees the website for the first time promoting the "12 Startups in 6 Months" is actually off-putting.

The reason I haven't clicked 'sign up' is I'd like to see a preview, any preview, before giving access to my account. Can the website ask for my twitter handle and crawl my recent likes as a start? Or a screenshot of somebody else's weekly email?
