When you add plugin extensions to a WordPress site, the functional possibilities are seemingly endless. There are over 12,000 plugins in the WordPress Repository alone, and thousands of them claim the title of OFFICIAL, ULTIMATE, BEST and VERY BEST. With multiple plugins that achieve the same goal, and the utter ease of installing plugin after plugin at will, how should we go about choosing which ones will best meet the needs of the website? How can plugins affect the functionality of our sites, both positively and negatively? This combination talk/public square discussion will cover where plugins come from, how to gauge their reputation for effectiveness and security, and how to assess your WordPress needs to decide which ones should make the cut and be added to your site. An open discussion will allow participants to share experiences with specific plugins and look to each other for guidance in solving their extension needs.
