Gyutae Park, of Winning the Web has a great list of WordPress plugins that they use on their site and consider “essential”. While I don’t agree with everything on the list personally, it is a massively helpful list for anyone looking for a little something to help them do a wide variety of things.
It’s got free plugins, it’s got pricey plugins, it’s got plugins that do things for just about every situation. It’s a damn fine list, and comes complete with full descriptions, and an occasional usage tip.
Here’s a small preview…
Breadcrumb Navigation XT
Adds a breadcrumb navigation showing the visitor’s path to his or her current location. I’m a huge fan of breadcrumbs (for both usability and SEO benefits) and highly recommend you implement this.
Force Word Wrapping
Prevents long words and URLs from horizontally stretching the page. Doesn’t it annoy you when a long URL messes up your template? This plugin prevents that from happening.
No Self Pings
Keeps WordPress from sending pings to your own site. This is pretty self explanatory. Why send pingbacks to your own posts?
At 41 plugins, with descriptions, it’s a bit of a read, but it’s well worth if you’re looking for a plugin that comes highly recommended by a successful blogger.
