title: Should I sign a non-competition clause in freelance contract?
body: <p>I'm trying to establish myself as an iPhone freelancer, and are currently negotiating with a startup about a bigger project. They have expressed that they want me to sign a non-competition agreement, so that I wouldn't be allowed to develop a similar product for companies in competition on the same geographical market. Needless to say, I don't really like this.</p>
  
  <p>Is this a common practice? If so, how common? Would you sign it?</p>
