We try to get results with available resources. An example of this can be seen in the footer for this web site. The theme used for this site was developed by Think Up Themes. Yes, we can remove the footer and make it look like the site was developed from scratch. However, why reinvent the wheel when we have tools like WordPress, Joomla, and a very deep pool of themes for little or no cost? We have specific skills, but it is very difficult to keep up with all technologies, so leveraging the experience and expertise of others benefits all of us and helps keep our costs down.
