The Twitter Advantage

I enjoy Facebook's format more than Twitter's, but recently I've experienced the Twitter Advantage. For the first time ever, I am in a critique group with an author/illustrator. Eileen is interested in graphic novels...a subject about which I am woefully ignorant. So I posted on Twitter: "Need graphic novel recommendations for children." A woman that I didn't know recommended Owly. Within minutes I got a message that I was being "followed" by Owly's creator, Andy Runton. The Twitter advantage doesn't limit you to connecting with friends, but allows you to search for people that have the information you need. How cool is that? So what's your preference, Facebook or Twitter?
