nice... Thanks, Joan. That's what I need to read right now. Cause I became in doubt whem I saw people in Twitter only concerned  talking about themselves. My vision is another, I see Twitter like a great tool to make us more closer, giving us more experience including to get in in the ultimates techniques, help people all around the world, etc, etc. And of course, everyone needs a leader and everyone can become a leader - anyhow, to become a leader you have to instruct and to inspire and be united..
