Nice implementation.

I don't like Facebook only logins, always good to offer the email & password reg option.

It would be nice if more than one quote was saved from an article, that it would become a bulleted list - with the page title pulled in as well for the list.

Maybe publishers/bloggers may be interesting in curating three or four good quotes from their articles into a short summary, then promote thorough QuoteRed.
