Perhaps an answer to the question “How does Quora evolve and expand?” See this Quora blog post for more details.
Quora Boards is basically a social bookmarking tool. Users can curate posts from Quora, links from around the Web, and other content. It’s similar to other sites like Pinterest — though Pinterest tends to be more visual and product-oriented — and Snip.it, (both of which Katie Boehret recently reviewed).
Introducing Boards wasn’t necessarily a play to broaden Quora’s appeal to a larger audience, Quora co-founder Charlie Cheever said in a phone interview. The intent was to give users tools they wanted — such as ways to feature their favorite Quora answers, or ways to acknowledge outside resources from the rest of the Web.
“It’s easier to put stuff on a Board than it is to write a five-paragraph answer,” Cheever said.
