We’re beginning to collect scripting best practice recommendations at http://www.scriptinganswers.com/essentials/index.php/category/best-practices/; you’ll also find additional PowerShell-specific best practices (including those related to PowerShell development, rather than scripting), at www.powershellcommunity.org.
Best practices are a way for you to benefit from the hard-earned lessons learned by others, and are usually a great way to produce more professional scripts than are easier to read and maintain. We’ll continue adding best practices; subscribe to the RSS feed at http://www.scriptinganswers.com/essentials to see new ones as they’re added.
