title: Sinatra vs. Rails
body: <p>I've worked through some of the Sinatra and Rails samples, but I'm having a hard time figuring out which features belong to which technology.</p>
  
  <p>What specifically do I gain by using Sinatra/Rails? Is it just ActionPack/ActionView? Correct me if I'm wrong, but I COULD just use Webrick/Mongrel and serve up my .erb files right? And I could use ActiveRecord technology in those files and still access post variables, session state and querystring variables right?</p>
  
  <p>So, what I'm asking you guys is, if I start with the PHP-like scenario above; Webrick + ERB + ActiveRecord, what do I gain by using Sinatra? And what do I further gain by using Rails?</p>
