I don't understand the last sentence in the quoted article: Before Facebook could take credit for its own wonderful ingenuity in creating the world's most needed Web site, thousands of Swedes were spreading pictures of IKEA showrooms all around the personal galaxy known as their profile pages. Before Facebook could take credit for creating Facebook, thousands of Swedes were spreading pictures of IKEA showrooms around Facebook? The video states this took place during the Autumn of 2009. The chronology and weird verb tense makes the sentence super confusing.
