title: Does Twitter support the 2-legged oAuth protocol?
body: <p>The oAuth protocol comes in two flavors, 3-legged and 2-legged protocols. The 3-legged one is about delegating user access rights to an application and is the one that gets the most attention on the web. The 2-legged version is used to authenticate an application against a service provider (Twitter in my case) with no specific user involved. </p>
  
  <p>In my application I need read only access to publicly available information, but at higher rate than the one available to unauthenticated request. There is no need for me to authenticate as a specific Twitter user.</p>
  
  <p>Does Twitter support the 2-legged version of oAuth?</p>

  <p>PS. The whitelisting alternative is an overkill for me and I rather not wait for the approval process.</p>
