We know many of you enjoy using Twitter to see what people are talking about and to let others know what you've been up to, whether it's sharing a YouTube video or checking in on your friend's tweets. To help you and your Twitter network stay connected no matter where you are on the web, we're excited to announce that Google Friend Connect has integrated with Twitter. This means that when you join a Friend Connected site, you can choose to use your Twitter profile, discover people you follow on Twitter who are also members of the site, and quickly tweet that you have found a cool website.
