Wordpress already makes blogging pretty easy but there is a single feature that makes it stand out from the other blogging platforms website development solutions.
I explain why plugins are great and how to add them to your Wordpress install at Wordcamp Boston, January 23rd, 2010
Plugins!
These little, useful creatures make it easy to add functionality to your blog without knowing any programming or html.
You can embed photo galleries, pull in your Twitter feeds, sell things from your site and well, just about anything you can imagine!
Plugins are easy to install. You sign into your self-hosted Wordpress account, go to "Plugins", click on "Add New" and you are presented with a list of popular, new plugins! You can also search the repository as well.
