title: Gem for Creating a full featured Blog in Rails Application
body: <p>I need a gem for creating a Blog in my rails Application. 
  We can write a whole bunch of our code, but for this small task an effective Gem is preferable. 
  Please suggest a good Gem for creating a blog that supports following features : </p>
  
  <pre><code>- Adding static  Blog contents. 
  - Feature to have image in blog
  - Visitor/Viewer must be able to comment/share the blog 
   ( will be much nicer if can be commented/shared via Facebook account)
  </code></pre>
  
  <p>I got  through Gems like : </p>
  
  <pre><code>-  "Redcloth" (for creating static web pages quickly; quite unsure 
      will it be able to handle image &amp; comment facility. )
  -  Gem "dynarex-blog" (for creating blog, but unable to find 
     good tutorial / proper documentation for integrating it with my Application).
  </code></pre>
