Looking to get into site flipping, from what i could gather wordpress composes the majority of the sold sites. I was hoping to specialize in Drupal, as I find it to be the best constructed CMS. I have one site up with Joomla and have been toying a little with Wordpress for IM purposes. Any thoughts on this? Should i go with Wordpress anyway or Drupal may work? Does it even matter that much the platform the site is built on?
