I have been blogging for more than 3 years now and I did not know it but I have been using a free Content Management Software.  This software makes it easy for me to manage my sites as well as update it and put a lot of add ons and widgets without me ruining the entire template. It so user friendly that not everybody knows that what we are manipulating whenever we change something is html. 

There was a time when it was not as user friendly as today when every little change that I had disaligns my margin and everything else. It was all in disarray. Good thing they changed it and now even kids can make their own sites as well.
