I am always open to more lists of WordPress Plugins:
Lunarpages Blog: Ten WordPress Plugins Worth Considering
The one I picked up from this list was WP Super Cache. My blog definitely needs a speed boost.
The next one I probably need to come back to is the Mobile Press. The only problem is that the link was broken. I’ll have to come back and research that later.
So, let me add a few of my own:
Ad Injection: Previously, I had tried to implement the ads manually into my theme. I found that they were slowing the site down. This plugin makes implementing ads correctly easier, and it gives you more options as well.
Edit Flow: While it is just me blogging, I still use this plugin to try to organize my posts. I have created a “Stub” status that I use when I find a topic that I want to write about. Then, I created a “Needs Research” status to indicate that I still have work to do before finishing the article. I also created a “Pending Review” status to remind myself to review the article one more time before publishing.
Jetpack: If you don’t already have this installed, WordPress should start to bug you about it. For me, it just means better looking stats. I need to delve into setting up some of the other features in it.
Yet Another Related Post Plugin: I need to spend more time on theming the related section, but this plugin seems to make the “related” section at the bottom pretty easy.
