Thanks for the ideas - we're going to implement some Machine-Learning Algorithms to help in clustering similar quotes together. But grouping by article like you said would also prove really useful. The point on bloggers/publishers is also good - we're looking to have Promoted Quotes which are quotes from new book from publishers. Thanks for your input!
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.
