title: Should I use Rails 3 for my application
body: <p>I have been a user of Rails for a while and used version 2.3.4 recently.</p>
  
  <p>Rails 3 Beta just came out recently and it seems have significant performance improvement especially with the merge with Merb.</p>
  
  <p>I'm planning on building an application that will take 4-6 months. Should I use Rails 3 for it starting with beta? Knowing that it will be buggy until full release? 
  Performance is definitely an important requirement for my application.</p>
  
  <p>You can help me if you can provide insight in the following questions:
  1- Do you think Rails 3 will be out in 4-6 months?
  2- Will it be easy to migrate code should I choose to go for Rails 2.3.5?</p>
