The wordpress platform is a lot of fun and it also lets you customise how your blog behaves. I have been using it for just over a year now and just love it.
I can use all the smarts of WordPress for free. WordPress is open-source, yay !
So in the interest of giving at least something back to the community, below is the list of plugins that I use after a year of playing around with what I want and need.
Add Meta Tags
Adds the Description and Keywords XHTML META tags to your blog’s front page and to each one of the posts, static pages and category archives. This operation is automatic, but the generated META tags can be fully customized. Also, the inclusion of other META tags, which do not need any computation, is possible. Please read the tips and all other info provided at the configuration panel. By George Notaras.
Adsense-Deluxe
Place Google AdSense ads in your WordPress Posts. Requires WordPress 1.5 or higer. For complete usage and configuration click on AdsenseDeluxe under the “Options” menu. By Acme Technologies.
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. By Matt Mullenweg.
