People buy from those they know, trust, and like. Salesmen chase people away. So don't sell on Twitter, just make friends. Talk about anything funny, interesting, fun, what you like and don't like, send out cool quotes.

You are gradually building relationships and becoming popular. More of my best Twitter tips are posted on my blog (link below).
