The funding round was led by Index Ventures, with Spark Capital and Union Square Ventures chipping in as well. The new funding will be used to support the company's growth, which -- according to Stack Exchange's data -- has been amazing. Stack Exchange started out as a Q&A site for developers, and now its network consists of 45 expert Q&A sites on a variety of topics, with nearly 20 million monthly unique visitors, 95 million page views and nearly 800,000 registered users.
The new funding comes after a significant search-algorithm change by Google, which had recently declared war on content farms. The change was good news for Stack Exchange, whose co-founder Jeff Atwood recently said that content syndicates have begun outranking the site's original content on Google Search.
