title: Sqlite3 vs Postgres vs Mysql - Rails
body: <p>I guess this has been brought up many times, but I'm bringing it up again!!!
  Anyway... In Ruby on Rails Sqlite3 is already setup and no extra picking and slicing is needed, but...
  after numerous readings here and other places, some say it's not scalable while others say it can actually be quite good at that. Some say MySQL is much better for bigger projects, while others think, just go with PostgreSQL.
  I'm interested in hearing your opinion on this. In two scenarios. One where you are starting a little website for news publishing website like CNN news, and the other scenario where you're creating a website similar to Twitter?</p>
