title: Why Is the Tweet Window Open In Pop Up Window With Specific Dimension
body: <p>I have an <code>&lt;a&gt;</code> tag with href="https://twitter.com/intent/tweet?text=@goomena Welcome to Goomena.com&amp;hashtags=goomena" when i click it, it is not opening in the existing window or in a new tab but it opens in a pop up window with specific dimensions.
  In my <code>&lt;a&gt;</code> tag <strong>i don't have any <em>target</em> property</strong> so i'm sure i'm not the one causing it.
  I like the effect but i would like to know how Twitter does it. I might use it in the future.
  Thanks in advance for your time and help.</p>
