title: R scrape a blog for Title, number of comments and 'likes'
body: <p>I'm trying to use R to grab some information from a few blogs.  The data I'd like to grab is:</p>
  
  <pre><code>1) Date posted
  2) Blog Post Title
  3) Number of Comments
  4) Number of Facebook likes.
  </code></pre>
  
  <p>This blog <a href="http://www.jamesaltucher.com/" rel="nofollow">here</a> has all the fields I'm looking to collect.</p>
  
  <p>Ideally I'd like a data frame that looks like this:</p>
  
  <pre><code>Post_Date      CommentCount       FB_Likes   Title
  2012-12-05          1                 629      The James and Claudia Kripalu Workshop– The Daily Practice: Finding Success From Within
    ...              ...                ...          ...
  </code></pre>
  
  <p>Is there a way to do this in R?  It seems like something that might be doable with <code>RCurl</code> but I'm not too familiar with <code>html/xml/js/etc</code>.</p>
  
  <p>So far this is what I have:</p>
  
  <pre><code>library(RCurl)
  library(XML)
  xmlTreeParse(getURI("http://www.jamesaltucher.com"))
  </code></pre>
  
  <p>when I run this I get errors that the opening and closing brackets don't match.</p>
  
  <p>NOTE: These are not my blogs so I don't have admin access to the blog or their FB account.</p>
