While plug-ins for the WordPress blogging platform are in abundant supply, I try not to depend on too many of them due to the fact that I don't want to have to worry about them breaking every time a new version of WordPress is released. That being said, there are four plug-ins as well as one adjustment to the post template itself that I feel are essential in order to have a great WordPress experience.

They are as follows:

• Dofollow - Allows you to remove "evil nofollow attribute" from your comments.
  
  
• SEO Title Tag - Makes is easy to optimize or customize title tags across your WordPress-powered blog.
  
  
• WP Mobile - A nifty plug-in creates a PDA friendly interface for your blog.
  
  
• Wordpress Automatic Upgrade - Automatically upgrades your WordPress version to the latest files provided using the 5 steps provided in the upgrade instructions.
  
  
• Customizing the "Read More Tag - Not a plug-in but more of an "adjustment" to the functionality of WordPress that allows you to customize the "read more" function.
