2) Why is this using my Google account? I'm 'logged in' according to the top right. I'm sure I didn't opt in - I didn't know the site. I didn't 'log in' anywhere - you're embedding stuff that refers to my real Google account, which isn't cool without saying what this is about.
3) Even if you're showing a Google product here and 2 is moot: If you're in private beta and I can 'add myself to the waiting list' - how am I 'logged in' in that case? That top row doesn't make sense?
Summary: The site is a landing page with a way to enlist for services that aren't spelled out. I don't blame the creators, but the submitter. Seems like 'schemer.com' gained a lot by using a favorable name here (at least I visited the site to read about something a la 'The little Schemer' or related stuff).
