I have made my site http://www.trabajoencostarica.com/ social (Email suscriptions, Feedburner RSS, Twitter, Facebook etc.).

Putting buttons for twitter and facebook on POSTS so people can re-tweet them or share them in facebook have pumped my site visits pretty much, also the buttons on my front page for email and RSS suscriptions have worked for me pretty much..I have a pretty decent email list of people expecting my posts now. So check them out..and let me know what you think.
