I thought it might be useful to let you know what WordPress plugins I am using, and why. Maybe some of these would be useful on your WordPress blog.
Akismet
Akismet checks your comments against the Akismet web service to see if they look like spam or not. You need a WordPress.com API key to use it. You can review the spam it catches under “Comments.” To show off your Akismet stats just put <?php akismet_counter(); ?> in your template. See also: WP Stats plugin.

Akismet
Akismet comes installed on every WordPress blog, but that doesn’t make it any less useful. It is very good at distinguishing spam from legitimate user comments, and I would set up any blog without turning it on.
All in One SEO Pack
This plugin provides some essential SEO configurations to your blog. I wouldn’t say you’ll get a ton of traffic from this, but it useful to put some of the basic SEO on your blog in an automated fashion.
Google Analytics for WordPress
This plugin makes it simple to add Google Analytics with extra search engines and automatic clickout and download tracking to your WordPress blog.
Google XML Sitemaps
It is very important for indexing purposes to have a sitemap on any site you create. This plugin will create a sitemap that is compatible with all the major search engines.
Postie
This is what I use to do my posting by email when I am away from home. It is much more configurable than the standard post by email options in WordPress.
Cronless Postie
This comes with Postie, but allows me to have the posts automatically publish on my blog, instead of having to visit a webpage or configure a cron job in order to process it.
RSS Link Tagger for Google Analytics
Modifies RSS permalinks to include utm query parameters, used by Google Analytics to track non-adwords advertising campaigns.
Sociable
This is what adds all those neat icons to the bottom of my posts, giving readers the option to Digg or Twitter the post.
Twitter for Wordpress
This gives me a widget with my Twitter feed in it that I can put in my sidebar. I like it better than the Twitter “badge” that you can grab from Twitter’s site, because that doesn’t match my blog theme.
WP to Twitter
This allows me to automatically send to Twitter any post that I publish.
Yet Another Related Posts Plugin
This isn’t doing much for me yet, but as I continue to post, this should include links at the bottom of each post listing related posts.
That’s all I have so far. I’m sure I’ll add more as time goes on. Do you have any suggestions on useful plugins? I’d love to hear them in the comments or on Twitter.
By the way, the easiest way to install plugins is to go through your WordPress dashboard and search for them. That is much more convenient than downloading the plugin from the author’s website, uploading it to your web host, and then activating it in the dashboard. Just a suggestion.
