Drupal for Bloggers: How can I achive getting such a little FB, Twitter, etc. Box on the left of my homepage?
You want to try something like the ShareBar in Drupal 7.


  The Drupal Sharebar module lets you easily add a "floating" social
  media submission bar on your website (like that found on Mashable)
  that includes share buttons for the most popular social media websites
  online such as Facebook, Twitter, and Google +1 Buttons.
