It's that simple... twitter is a powerful business tool, but only if you use it correctly. Try several of these ideas, not just one, and be consistent. Remember, success does not come to 'those who wait'... it comes to those who go out and get it.
1. Write good notes. 140 characters may challenge you, but truth is - when you learn to convey the right message in a space that small, you achieve more attention than when you ramble.
2. Remember your audience - it's not about you. How many times have you heard that? Thousands, if you're paying attention. It's true. It's not about you. It's about me. If I'm your audience. It's not about me, if I'm not your audience. Be selective in what you share and always remember who is watching.
3. Share. What else can I say? Share the good stuff. Share humor. Share links.
