title: Design patterns to avoid
body: <p>A lot of people seem to agree, that the Singleton pattern has a number of drawbacks and some even suggest avoiding the pattern entirely. There's an <a href="https://stackoverflow.com/questions/137975/what-is-so-bad-about-singletons">excellent discussion here</a>. Please direct any comments about the Singleton pattern to that question. </p>
  
  <p><strong>My question</strong>: Are there other design patterns, that should be avoided or used with great care?</p>
