title: 2 Spaces or 1 Tab, what's the standard for indentation in the Rails Community?
body: <p>I've noticed that most of the HTML/XML/HAML that gets generated from plugins uses 2 spaces instead of 1 tab.  I use textmate and have tabs set to 4 spaces for HAML/HTML/XML and 2 spaces for Javascript/Ruby, but I only have to press the tab key once to get nice indentation.  Pressing the space bar twice and delete twice seems like too much work :p.</p>
  
  <p>Do you manually type two spaces, or is some middle layer converting tabs to two spaces?  Or do just a few of you use tabs?</p>
