A blog is a frequently updated, personal website featuring diary-type commentary and links to articles or other Web sites. Blogs range from the personal to the political, and can focus on one narrow subject or a whole range of subjects.
 

FEATURES

No rebuilding - Changes you make to your templates or entries are reflected immediately on your site, with no need for regenerating static pages.

Pages - Pages allow you to manage non-blog content easily, so for example you could have a static "About" page that you manage through WordPress. For an idea of how powerful this is, the entire WordPress.org site could be run off WordPress alone. (We don't for technical mirroring reasons.)

Links -- Links allows you to create, maintain, and update any number of blogrolls through your administration interface. This is much faster than calling an external blogroll manager.

Themes - WordPress comes with a full theme system which makes designing everything from the simplest blog to the most complicated webzine a piece of cake, and you can even have multiple themes with totally different looks that you switch with a single click. Have a new design every day.

Comments - Visitors to your site can leave comments on individual entries, and through Trackback or Pingback can comment on their own site. You can enable or disable comments on a per-post basis.

Spam protection - Out of the box WordPress comes with very robust tools such as an integrated blacklist and open proxy checker to manage and eliminate comment spam on your blog, and there is also a rich array of plugins that can take this functionality a step further.

Full user registration - WordPress has a built-in user registration system that (if you choose) can allow people to register and maintain profiles and leave authenticated comments on your blog. You can optionally close comments for non-registered users. There are also plugins that hide posts from lower level users.

Password Protected Posts - You can give passwords to individual posts to hide them from the public. You can also have private posts which are viewable only by their author.

Multiple authors - WordPress' highly advanced user system allows up to 10 levels of users, with different levels having different (and configurable) privileges with regard to publishing, editing, options, and other users.

Bookmarklets - Cross-browser bookmarklets make it easy to publish to your blog or add links to your blogroll with a minimum of effort.

Ping away - WordPress supports pinging Ping-O-Matic, which means maximum exposure for your blog to search engines.
